Crack-Tip Fields of a Crack Impinging upon the Yielding/Debonding Slippage in Anisotropic Body

摘要: This paper presents a fundamental solution for crack impinging normally upon the slippage in anisotropic materials under tensile loading. The could occur form of yielding (e.g., well-bonded ductile layer with plastic yielding) or debonding weak, sliding-free one). A superposition method is employed to explicitly solve problem which combines an elastic homogeneous medium, continuous distribution dislocations represent slippage, and appendix offsets stress on faces induced by dislocations. procedure reduces singular integral equation can be numerically solved using Chebyshev polynomials. Numerical implementations are performed analyze influence cracking redistribution near tip bodies. It found that redistributes ahead tip. presence lowers high concentration stresses also concluded appears more effective lowering than yielding.
