Abstract

We propose a simple yet effective method to determine the compressibility and the shear compliance of a pore possessing an (n + 1)-fold axis of symmetry with n ≥ 2 embedded in an infinite isotropic elastic body. The conformal mapping function which maps the exterior of the pore onto the exterior of the unit circle in the image plane contains an arbitrary number of terms. When the mapping function has N+1 terms, the compressibility and shear compliance are found by solving, respectively, sets of N and 2N coupled linear algebraic equations. Detailed numerical results for the compressibility and shear compliance of equilateral polygonal holes and a five-pointed star shaped hole are presented to demonstrate the proposed solution method.

通过使用包含任意项数的共形映射函数,获得具有 (n + 1) 倍对称轴的孔隙的可压缩性和剪切顺应性
我们提出了一种简单而有效的方法,用于确定嵌入无限各向同性弹性体中具有 n ≥ 2 的 (n + 1) 倍对称轴的孔隙的可压缩性和剪切顺应性。将孔隙外部映射到图像平面单位圆外部的共形映射函数包含任意数量的项。当映射函数有 N+1 项时,通过分别求解 N 个和 2N 个耦合线性代数方程组,可求得压缩性和剪切顺应性。本文给出了等边多边形孔和五角星形孔的可压缩性和剪切顺应性的详细数值结果,以演示所提出的求解方法。

期刊介绍: The International Journal of Solids and Structures has as its objective the publication and dissemination of original research in Mechanics of Solids and Structures as a field of Applied Science and Engineering. It fosters thus the exchange of ideas among workers in different parts of the world and also among workers who emphasize different aspects of the foundations and applications of the field. Standing as it does at the cross-roads of Materials Science, Life Sciences, Mathematics, Physics and Engineering Design, the Mechanics of Solids and Structures is experiencing considerable growth as a result of recent technological advances. The Journal, by providing an international medium of communication, is encouraging this growth and is encompassing all aspects of the field from the more classical problems of structural analysis to mechanics of solids continually interacting with other media and including fracture, flow, wave propagation, heat transfer, thermal effects in solids, optimum design methods, model analysis, structural topology and numerical techniques. Interest extends to both inorganic and organic solids and structures.
