Coupling of finite element method with material point method by local multi-mesh contact method
Yanping Lian,Xiong Zhang,Yan Liu +2 more
TL;DR: A method to handle the contact interaction between the MPM body and the FEM body is proposed, which is implemented on the background grid of MPM and a hexahedral element is incorporated into 3D explicit MPM code MPM3D®.
Journal ArticleDOI
Incompressible material point method for free surface flow
TL;DR: Numerical examples including dam break, oscillation of a cubic liquid drop and a droplet impact into deep pool show that the proposed incompressible material point method is much more accurate and efficient than the weakly compressiblematerial point method in solving free surface flow problems.
Journal ArticleDOI
An adaptive finite element material point method and its application in extreme deformation problems
Yanping Lian,Xiong Zhang,Yan Liu +2 more
TL;DR: In this paper, an adaptive finite element material point method is developed for modeling the dynamic behavior of material under extreme loading, where the body is initially discretized by finite elements, and then the elements with large strain are adaptively converted into MPM particles based on their degree of distortion or plastic strain during the solution process.
Journal ArticleDOI
A meshfree Hermite‐type radial point interpolation method for Kirchhoff plate problems
TL;DR: In this paper, a mesh-free computational method is proposed to solve the Kirchhoff plate problems of various geometries, where the deflection of the thin plate is approximated by using a Hermite-type radial basis function approximation technique.
