带裂纹非均匀各向异性材料的双周期弹性焊接第一基本问题
First Fundamental Plane Elasticity Welding Problem of Inhomogeneous Anisotropic Materials with A Doubly-periodic Set of Cracks
摘要
Abstract
Doubly periodic plane elasticity problem is very useful in elasticity and fracture of isotropic and anisotropic elastic materials.In this paper,the first fundamental plane elasticity welding problem is investigated.Employing the complex variable function method,solving this problem is transferred into seeking analytic functions which fit certain boundary value problems.Further,under some general restrictions,Sherman's transform for doubly-periodic elasticity theory of homogeneous anisotropic materials to that of inhomogeneous materials is developed.Then,using the general representation for the solution,the boundary value problem is reduced to a normal type singular integral equation with a Weierstrass zeta kernel along the boundary of cracks and welding interface,and the unique solvability of which is established.关键词
