María De Los Ángeles Herrera GarridoDogwood B
A Python code based on a semianalytic procedure for the analysis of singular stress and displacement fields in anisotropic multi-material corners in generalized plane strain is developed. Open and closed (periodic) multi-material corners formed by isotropic, transversely isotropic or anisotropic materials with perfectly bonded interfaces or in frictionless or frictional sliding contact are considered. Many kinds of boundary conditions as free, clamped, displacement allowed or not in any given direction, and frictionless or frictional sliding contact are covered. This computational tool may help researchers who need to know the singularity exponents and the singular eigenfunctions for stresses and displacements for a corner, e.g., to improve or check their numerical results by FEM, or to verify their analytic formulas of eigenequations developed for specific stress singularity problems. With the aim of sharing this useful tool, it has been made available on research group website, where the user can introduce the corner problem parameters and the corner singularity problem is solved by a high-performance computing server.
