Meshfree generalized finite difference methods in soil mechanics—part II: numerical results

In geotechnical engineering, simulations are of utmost importance. Due to large deformations, meshfree methods are more suitable than classical meshbased methods. Nevertheless, they have to be validated on the laboratory scale in order to guarantee reliable conclusions for real life applications. In this contribution, we complete the theoretical description of the two novel meshfree generalized finite difference methods Finite Pointset Method (FPM) and Soft PARticle Code (SPARC) by numerical results for the standard benchmark problems oedometric and triaxial test. We focus on the quality of the results as well as on the rate-independent character of the numerical implementation of the nonlinear barodesy model for sand.
