Improved robustness for nearly-incompressible large deformation meshfree simulations on Delaunay tessellations

Computer Methods in Applied Mechanics and Engineering Volume 293, 15 August 2015, Pages 348 – 374 A. Ortiz-Bernardin,  M.A. Puso and N. Sukumar Abstract A displacement-based Galerkin meshfree method for large deformation analysis of nearly-incompressible elastic solids is presented. Nodal discretization of the domain is defined by a Delaunay tessellation (three-node triangles and four-node tetrahedra), which is used to…
