Abstract

This work investigates the performance of various remeshing and remapping algorithms for the finite element simulation of plane-strain large deformation elastoplastic problems using a decoupled arbitrary Lagrangian-Eulerian approach. The remeshing algorithms, which are herein adjusted to the needs of elastoplastic deformation analyses, are the Elastic Rebound approach, the Spring Analogy Method and the Radial Basis Functions. The remapping algorithms are the Inverse Distance Algorithm and two data interpolation schemes, namely the Radial Basis Point Interpolation Functions and the Radial Basis Functions. The efficiency and robustness of the algorithms are assessed by simulating the penetration of a rigid flat punch.
