A digital systematization of meshfree method and its applications to elasto-plastic infinitesimal deformation analysis
A meshfree approach to two-dimensional elasto-plastic analysis implementing the element-free Galerkin is presented. Although a set of mesh data for evaluating the spatial integrals of the Galerkin weak form is usually necessary, a regular grid of cells are constructed within the program to alleviate the burden of meshing arbitrarily shaped domains. Infinitesimal deformation involving material nonlinearity was examined and shown to predict the deformation state as competently as the finite elements. Furthermore, Computer Aided Design/Computer Aided Engineering (CAD/CAE) seamless system and digital analysis procedures for digital images are presented which aid in the creation of the domain data, and are believed to be practical applications for the meshfree methods.
