Numerical aspects of phase field models for low-temperature fracture in asphalt mixtures
Case Studies in Construction Materials, 2023 Unlike the cohesive interface element model, the phase field model (PFM) is a newly developed computational model which provides a unified approach to predicting crack nucleation, propagation, coalescence and branching without any ad-hoc criterion.

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.

Quasi-Static Indentation test Analyses of CFRP laminate using quasi three-dimensional XFEM
Nihon Kikai Gakkai ronbunshu, 2021 CFRP laminates subjected to out-of-plane load may have complex damage such as delamination, matrix crack and fiber failure. In this study, damage propagation analyses for Quasi-Static Indentation (QSI) tests were performed by static implicit method using
