Modeling transverse cracking in laminates with a single layer of elements per ply

This study aims to bridge the gap between classical understanding of transverse cracking in [0/90]s laminates and recent computational methods for the modeling of progressive laminate failure. Specifically, the study investigates under which conditions a three-dimensional model with cohesive cracks can reproduce the in situ effect for the ply...

An efficient computational model for CO2 flow in porous media

This paper presents an efficient computational model for the simulation of fully coupled two-phase flow in a deformed partially saturated formation. Focus is placed on modeling the flow of a CO2 plume in a porous medium. The numerical procedure is based on coupling between the Level-set method (LS) and the extended finite element method (XFEM)....

A continuous-discontinuous approach to simulate failure of quasi-brittle materials

A continuous-discontinuous approach to simulate failure is presented. The formulation covers both diffuse damage processes in the bulk material as well as the initiation and propagation of discrete cracks. Comparison with experimental data on layered sandstone shows that the modeling strategy accurately captures the physics of the failure process.
