Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TLDR
In this article, fracture mechanics is introduced into finite element analysis by means of a model where stresses are assumed to act across a crack as long as it is narrowly opened, which may be regarded as a way of expressing the energy adsorption in the energy balance approach.About:

A thermodynamics-based cohesive model for discrete element modelling of fracture in cemented materials
TL;DR: In this paper, a discrete modeling approach employing a new cohesive model is proposed to investigate the failure response of cemented materials, based on a generic thermodynamic framework for coupling damage mechanics and plasticity theory.

Numerical study of the deformation and fracture behavior of porous Ti6Al4V alloy under static and dynamic loading
Nityagopal Biswas,Jow-Lian Ding +1 more
TL;DR: In this article, the authors used numerical simulations to gain insights on the observed material behavior and a general understanding of the dynamic responses of porous metals, showing that the pore in general could serve as both a failure initiator and an inhibitor.
