Most popular strategies are based on a master–slave coupling, in which contact forces are computed to prevent the penetration of SPH particles into the Finite Element meshes [9–11]. Each method proposed has its own specificity (see for instance [12] where FE nodes are considered as SPH par...

External approximations are a generalization of Finite Element Method (FEM) in terms that:absolutely arbitrary geometrical shapes can be used as “finite elements” basis functions which approximate field of interest in the part volume can be of arbitrary class and are independent of the volume ...
A rigid-plastic element-free Galerkin-finite element(EFG-FE) coupling method was developed for the numerical simulation of plane lateral extrusion process. 应用刚塑性耦合无网格-有限元法,对平面侧向挤压过程进行数值模拟。 更多例句>> 3) EFGM-FEM coupling method ...
developed with the use of Maple. Each section serves as a stand-alone description, but it is apparent how each conveniently leads to the other techniques. It is recommended that the reader begin with the finite element method, as this serves as the primary basis for defining the method of ...

Recently, a great number of studies have been carried out to model soft tissue deformation in contact with surgical instruments to aid the development of surgical simulators. Precise methods to model the soft tissue such as the Finite Element Method (FEM) lack accuracy in large deformations....
and determining the chip forming mechanism and final morphology. Finite element method (FEM) models are proven to be adequate for metal cutting simulations up to some extent but still exhibit several shortcomings. During the past few years, a shift towards meshless methods was noticed, in order ...
The method is very similar to the hp-cloud method. Generally, PUFEM shape functions are based on Lagrange polynomials, while the general form of the hp-cloud method also includes the MLS-approximation. Strouboulis et al. [91] pointed out in their generalized finite element method (GFEM) ...
