Studies have found that the widely-used one-pass node-to-segment (NTS) algorithm for
contacts fails to pass the contact patch test. Solution errors at the contacting surfaces …

A two-phase one-layer stabilised node-based strain-smoothing Particle Finite Element
Method (SNS-PFEM) was previously proposed, but it lacked the capability to simulate water …

Traditional particle finite element method (PFEM) with a six-node triangular (T6) element
using an iteration algorithm often suffers from high computational costs and non …

This study presents a robust numerical method for the computational homogenization
analysis of microstructures at limit state. The periodic boundary conditions for asymmetric …

It was recently found that the stable node-based smoothed finite element method (SNS-
FEM) does not have the advantage of NS-FEM in avoiding volumetric locking and thus …

The grid-based multi-velocity field technique has become increasingly popular for simulating
the Material Point Method (MPM) in contact problems. However, this traditional technique …

A landslide is a common natural disaster that causes environmental damage, casualties and
economic losses, which seriously affects the sustainable development of society. In …

非均匀层状边坡稳定是岩土工程中的重要问题之一. 基于理想塑性上限和下限的极限分析方法是
分析此类问题的常用方法之一. 近期提出的基于混合常应力–光滑应变单元的极限分析方法 …

The stability of 2D elliptical tunnels in cohesive-frictional soils are studied by using upper
bound approach of limit analysis based on smoothed finite element method (SFEM) and …
