In this report,the stability of the moving least squares(MLS)approximation is analyzed.It is shown that the stability deteriorates severely as the nodal spa
The explicit material point method(EMPM)[1]works well in simulating extreme deformation problems,where the finite element method(FEM)often encounters mesh d
An additional feature for modelling cracks in Material Point Method(MPM)is presented.The new method,called eXtended Material Point Method(XMPM),enriches the
