1.[期刊论文]Glulam theory from statistical engineering mechanics

标题翻译:来自统计工程力学的Glulam理论

期刊：《Australian Journal of Structural Engineering》 | 2020 年第 2 期

摘要：ABSTRACT In an earlier paper by the author it was mooted that glulam assembly bending strengths could be derived from the data provided by testing of bonded lamination pairs. The test concept separates the mechanics and statistics of knot, sloping grain and any finger joint reinforcement brought about by stress transfer mechanisms from one lamination to adjoining laminations by simulating the conditions that exist in a glulam assembly. The focus was primarily on a standard assembly, of overall depth 300 mm, made up of 10 × 30 mm thick laminations, breadth 65 mm. In this paper, the basic ideas are reviewed in greater depth but particularly from the perspective of how glulam assemblies are affected by beam volume.

2.[期刊论文]Concepts for E-Assessments in STEM on the Example of Engineering Mechanics

标题翻译:在工程力学晶体中的电子评估的概念

期刊：《International Journal of Emerging Technologies in Learning (iJET)》 | 2020 年第 12 期

摘要：We discuss if and how it is possible to develop meaningful e-assessments in Engineering Mechanics. The focus is on complex example problems, resembling traditional paper-pencil exams. Moreover, the switch to e-assessments should be as transparent as possible for the students, i.e., it shouldn’t lead to additional difficulties, while still maintaining sufficiently high discrimination indices for all questions. Example problems have been designed in such a way, that it is possible to account for a great variety of inputs ranging from graphical to numerical and algebraic as well as string input types. Thanks to the implementation of random variables it is even possible to create an individual set of initial values for every participant. Additionally, when dealing with complex example problems errors carried forward have to be taken into account. Different approaches to do so are detailed and discussed, e.g., pre-defined paths for sub-questions, usage of students’ previous inputs or decision trees. The main finding is that complex example problems in Engineering Mechanics can very well be used in e-assessments if the design of these questions is well structured into meaningful sub-questions and errors carried forward are accounted for.

摘要翻译：我们讨论是否可以在工程力学中开发有意义的电子评估。重点是复杂的示例问题，类似传统的纸铅笔考试。此外，对电子评估的切换应该尽可能透明，即学生，即，它不应该导致额外的困难，同时仍然保持所有问题的足够高的歧视指数。示例问题以这样的方式设计，即可以考虑从图形到数字和代数以及串输入类型的各种输入。由于随机变量的实现，甚至可以为每个参与者创建一个单独的初始值集。此外，在处理复杂的示例问题时，必须考虑向前推出的错误。这样做的不同方法是详细和讨论的，例如，预定义的子问题的路径，学生以前的输入或决策树的使用。主要发现是，如果这些问题的设计很好地构造成有意义的子问题，则可以在电子评估中用于电子评估中的复杂示例问题。

4.[期刊论文]Roadway Engineering Mechanical Properties and Roadway Structural Instability Mechanisms in Deep Wells

标题翻译:深井巷道工程力学特性及巷道结构失稳机理

期刊：《KSCE journal of civil engineering》 | 2018 年第 5 期

摘要：We proposed a new classification method for stress-bearing structures in very-deep roadways. We conducted tests for roadwayengineering mechanical properties, including rock mechanical tests and ground stress measurement of two caverns in very-deep wells. We suggested a classification method for stress-bearing structures based on shear stress. Tests revealed that rock strength in the shear direction was the lowest; the stress distributions of acoustic emission and hollow inclusion were highly similar. Based on the roadway-engineering mechanical properties of two caverns and numerical simulation and in-situ tests, the key bearing structures were classified based on the concentrated shear stress. In deep caverns, shear stress was more concentrated on the softer surrounding rock, the key bearing structure areas, and the more seriously fractured surrounding rocks. Using the loose circle in-situ test, we compared the classification method of the key bearing structures with other classification methods. The results revealed agreement with the classification methods used for the key bearing structures. The deformation in-situ test showed that the strata convergence of concentrated shear stress areas developed quickly. Therefore, the phenomena of concentrated shear stress and the expanded range of key bearing structures are the structural instability mechanisms of deep roadways.

摘要翻译：我们提出了一种在深井巷道中承载结构的新分类方法。我们对道路工程机械性能进行了测试，包括岩石力学测试和非常深的井中两个洞穴的地面应力测量。我们提出了一种基于剪应力的承载结构分类方法。试验表明，剪切方向的岩石强度最低。声发射与中空夹杂物的应力分布高度相似。基于两个洞室的巷道工程力学性能，并通过数值模拟和现场试验，根据集中剪应力对关键支座结构进行了分类。在深层洞穴中，剪应力更多地集中在较软的围岩，关键的承压结构区域以及破裂程度更大的围岩上。使用松散圆原位测试，我们将关键轴承结构的分类方法与其他分类方法进行了比较。结果表明与用于关键轴承结构的分类方法一致。原位变形试验表明，集中剪切应力区域的地层收敛迅速。因此，集中剪应力现象和关键支护结构的扩展范围是深部巷道的结构失稳机理。

The reforms implemented included online homework, online examples, online videos, an online lecture, and in-class activities. All of the curricular changes were aimed at reducing the cost of instruction while simultaneously mitigating the negative impacts on student learning associated with large class sizes.;Cumulatively, the cost of the reforms was estimated at ;Student learning was measured indirectly through the use of course surveys and evaluations. It was found that the student scores on the final exam were significantly higher in 2010 with an average of 62% as compared to 2009 with an average of 57% (p = .019). It was also found that the homework grades were higher in 2010 with an average of 92% as compared to 2009 with an average of 81% ( p = .000).

9.[学位论文]Theoretical and computational concepts in engineering mechanics.

标题翻译:工程力学中的理论和计算概念。

摘要：Traditional finite element methods and boundary element methods cannot accurately analyze non-smooth problems in engineering continuum mechanics. In non-smooth problems, either the domains have sharp boundaries including cracks and comers or mixed boundary conditions are specified. The common feature of these problems is singularity. In engineering applications, non-smooth problems include those associated with fracture mechanics, and also those involving composite materials in which interface conditions may include singularities. Solution of these problems are crucial to the design of safe, efficient components.;In this dissertation, a new theory for boundary value problems has been developed. This theory which is called the theory of fundamental eigen-expansion , introduces fundamental deformations as a basis for general solution. This theory not only explains direct integral equation formulations and BEM, but also gives a new formulation for non-smooth problems.;The theory of fundamental eigen-expansion uses the concept of orthogonal functions in boundary value problems. We prove that the fundamental eigenmodes exist and are orthogonal with respect to an arbitrary weight function. Using the appropriate weight function is the key to solving non-smooth problems. These eigenmodes are the spectrum of the direct integral equation.;The new theory gives two convergence criteria. One is global convergence and the other is local. Global convergence brings the concept of "convergence in mean" which is a popular property in the theory of orthogonal functions. Local convergence relates to the idea of "uniform convergence" and explains the behavior of solutions for discontinuity on the boundary, which is a common feature of non-smooth problems.;In this dissertation, a traction oriented FEM formulation is also developed which accounts for singularities. This formulation follows the theory of fundamental eigen-expansion. By condensation for internal nodes we can have an exact correspondence to the BEM equations. The FEM equation deals with symmetric matrices which shows that the spectrum is real. The theory of fundamental eigen-expansion shows the relation of BEM and the new FEM. We can say that the new FEM is an approximated BEM where volume integral is transformed on the boundary numerically by condensation.;Beyond its usefulness in solving non-smooth problems, the theory of fundamental eigen-expansion gives a better understanding of boundary value problems which directly affects computational mechanics methods such as BEM and FEM.

摘要翻译：传统的有限元法和边界元法无法准确地分析工程连续力学中的非光滑问题。在非光滑问题中，要么区域具有清晰的边界（包括裂缝和拐角），要么指定了混合边界条件。这些问题的共同特征是奇点。在工程应用中，非光滑问题包括与断裂力学相关的问题，以及涉及界面条件可能包含奇点的复合材料的问题。解决这些问题对于设计安全，有效的零件至关重要。本文为边值问题开发了一种新的理论。该理论称为基本本征扩展理论，它引入了基本变形作为一般解的基础。该理论不仅解释了直接积分方程的公式和边界元法，而且为非光滑问题提供了新的公式。基本本征展开理论在边界值问题中使用了正交函数的概念。我们证明基本本征模存在并且相对于任意权函数正交。使用适当的权重函数是解决非平滑问题的关键。这些本征模是直接积分方程的谱。新理论给出了两个收敛准则。一个是全球趋同，另一个是局部。全局收敛带来了“均值收敛”的概念，这是正交函数理论中的一个流行特性。局部收敛涉及“均匀收敛”的思想，并解释了边界上不连续性的解的行为，这是非光滑问题的一个共同特征。奇点。这种表述遵循基本本征扩展理论。通过缩合内部节点，我们可以与BEM方程完全对应。有限元方程处理对称矩阵，表明谱是实数。基本特征扩展理论表明了边界元法和新的有限元法的关系。可以说，新的有限元法是一种近似的边界元法，其中体积积分通过凝聚在边界上进行数值转换;除了其在解决非光滑问题方面的用处之外，基本本征展开理论还可以更好地理解边界值问题直接影响诸如BEM和FEM的计算力学方法。

10.[学位论文]Sensitivity boundary integral equations with applications in engineering mechanics.

标题翻译:灵敏度边界积分方程及其在工程力学中的应用。

摘要：In sensitivity analysis for problems involving thin domains or domains with cracks, conventional boundary integral equations must be supplemented and/or replaced by hypersingular ones. This is due to the fact that the conventional equations become nearly-degenerate for thin domains and actually degenerate for cracks. Such degenerate character follows from the close proximity to each other, or actual coincidence, of two defining surfaces in each case. Hypersingular boundary integral equations for sensitivity analysis are developed in two forms in this thesis, using a global regularization and a local regularization. The regularizations are facilitated by observing that the singularity order of the sensitivity BIE. formulas is no more than that of the ordinary BIE formulas. One motivation for this work is the computation of stress-intensity-factor sensitivities with respect to crack-growth. Other motivations would include optimization and design applications wherein sensitivities would be needed, but would otherwise be unavailable, for any reason, from conventional integral equations alone. In this thesis, examples of stress-intensity-sensitivities with respect to the size of a crack are given. Specifically, sensitivity values for a circular bar with an embedded penny-shaped crack under tension, bending, and torsion loadings are obtained and shown to be accurate. These examples verify the formulas and the codes developed in this dissertation.

摘要翻译：在涉及薄区域或带有裂纹的区域的问题的敏感性分析中，必须用超奇异方程补充和/或替换常规边界积分方程。这是由于以下事实：常规方程对于薄区域几乎退化，而对于裂纹实际上退化。在每种情况下，这种退化的特征是由于两个限定表面彼此非常接近或实际重合。本文采用全局正则化和局部正则化两种形式开发了用于灵敏度分析的超奇异边界积分方程。通过观察灵敏度BIE的奇异阶可以促进正则化。公式不超过普通BIE公式。这项工作的动机之一是计算关于裂纹扩展的应力强度因子敏感性。其他动机将包括优化和设计应用程序，其中需要灵敏度，但由于某种原因否则将无法单独从常规积分方程中获得灵敏度。在本文中，给出了关于裂纹尺寸的应力强度敏感性的示例。具体地，获得了在张力，弯曲和扭转载荷下具有嵌入的便士形裂缝的圆棒的灵敏度值，并且该灵敏度值显示为准确的。这些例子验证了本文开发的公式和代码。
