Journal ArticleDOI
A unified stability analysis of meshless particle methods
TL;DR: In this article, a stability analysis of meshless methods with Eulerian and Lagrangian kernels is presented, and three types of instabilities are identified in one dimension: an instability due to rank de ciency, a tensile instability and a material instability.
Journal ArticleDOI
A multiple-quadrature eight-node hexahedral finite element for large deformation elastoplastic analysis
TL;DR: In this article, a multiple-quadrature underintegrated hexahedral finite element, which is free of volumetric and shear locking, and has no spurious singular modes, is described and implemented for nonlinear analysis.
Journal ArticleDOI
A Coupled Meshfree/Finite Element Method for Automotive Crashworthiness Simulations
TL;DR: In this article, a coupled mesh-free/finite element solver for automotive crashworthiness simulations is presented. But, it is not suitable for large-scale industrial applications.
Journal ArticleDOI
Triangular composite finite elements
TL;DR: Composite triangles consisting of four three-node triangles originally proposed by Camacho and Ortiz are studied and it is shown that the original element does not satisfy the Babuska–Brezzi condition nor pass the patch test.
Journal ArticleDOI
Numerical modeling of composite solids using an immersed meshfree Galerkin method
Cheng-Tang Wu,Yong Guo,E. Askari +2 more
TL;DR: A non-conforming meshfree Galerkin method for the elasticity interface problem is devised and is shown to satisfy an optimal error estimate in the energy norm.
