CHILES 2: A Finite Element Computer Program That Calculates the Intensities of Linear Elastic Singularities in Isotropic and Orthotropic Materials.

摘要

CHILES 2is a finite-element computer program that calculates the strength of singularities in linear elastic bodies. A generalized quadrilateral finite element that includes a singular point at a corner node is incorporated in the code. The displacement formulation is used and interelement compatibility is maintained so that monotone convergence is preserved. Plane stress,plane strain,and axisymmetric conditions are treated. Isotropic and orthotropic crack tip singularity problems are solved by this version of the code,but any type of singularity may be properly modeled by modifying selected subroutines in the program.
