The Applications of Meshfree Particle Methods at the Nanoscale [PDF]
, 2005 Since meshfree particle methods are beneficial in simulating the problems involving extremely large deformations, fractures, etc., these methods become attractive options in multiscale modeling, especially when approaching a large number of atoms. In this paper, we propose preliminary research on applying meshfree particle methods to solve nanoscale ...

Application of Meshfree Method in Geotechnical Engineering
, 2013 Numerical methods are often used to solve complex engineering problems. Among them, finite element method (FEM) is the most widely used method. However, FEM can only model problems with finite deformation as divergence of solution may occur if there is ...
