Research on Fatigue Crack Propagation of 304 Austenitic Stainless Steel Based on XFEM and CZM
Metals, 2020 The fatigue crack propagation of 304 austenitic stainless steel was studied both by experiments and numerical simulations. Two methods were applied to simulate the crack propagation: the extended finite element method (XFEM) and the cohesive zone model ...

Implicit DEM analyses of size and shape effects on crushing strength of rockfill particles
Yantu gongcheng xuebao, 2023 An implicit version of discrete element method (DEM) called non-smooth contact dynamics (NSCD) is used to simulate the crushing process of single rockfill particle under one-dimensional (1D) compression.

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.
