摘要

文章考虑了 Cowin-Nunziato 线性模型的平面变形情况，该模型描述了带有空隙的弹性体的静态平衡。该模型对应的二维方程组的一般解由任意两个谐函数和亥姆霍兹方程的解表示。在一般解的基础上，利用基本解的方法，提出了一种可以近似求解相应边界值问题的算法。利用该算法构建了带有圆孔的方形域的各种边界值问题的近似解。

Approximate solution of plane problems about stress concentrations in elastic bodies with voids

The article considers the case of plane deformation for the Cowin–Nunziato linear model, which describes the static equilibrium of elastic bodies with voids. The general solution of the system of two-dimensional equations corresponding to this model is represented by any two harmonic functions and the solution of the Helmholtz equation. Based on the general solution and using the method of fundamental solutions, an algorithm is presented that allows one to approximately solve the corresponding boundary value problems. Approximate solutions of various boundary value problems for square domains with circular holes are constructed using this algorithm.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
