EXPLOITING AND VERIFYING USER-DEFINED MATERIAL MODEL IN LS-DYNA
摘要
Abstract
When the required material model does not exist in LS-DYNA material library, users can customise the material and create new calculator of LS-DYNA for solving the problem. Semi-implicit return mapping algorithm represents its good usage when the numerical algorithm is required to calculate constitutive equations in problem solving. In this paper, through the derivation of a solving formula of a simple and ideal elastic-plastic model ,we further elaborate this method as well as the basic course of compiling the material program, and a one-element model is used to have verified the correctness of the complied program.关键词
