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:

Computational analysis of mixed-mode fatigue crack growth in quasi-brittle materials using extended finite element methods
TL;DR: In this article, an extended finite element method (XFEM) containing strong discontinuity within elements is introduced and implemented in the commercial general purpose software ABAQUS, which allows introducing a new crack surface at arbitrary locations and directions in elements.

Automatic modelling of cohesive crack propagation in concrete using polygon scaled boundary finite elements
TL;DR: An automatic cohesive crack propagation modelling methodology for quasi-brittle materials using polygon elements is presented in this article, where each polygon is treated as a subdomain that is modelled by the scaled boundary finite element method (SBFEM).

Numerical modeling tensile failure behavior of concrete at mesoscale using extended finite element method
TL;DR: In this article, a 2D mesoscale analysis is performed to investigate the fracture process of concrete subjected to uniaxial tension by using the extended finite element method, and good agreement is obtained between the experimental observation and the present simulation results.

Hydraulic fracturing: Computational modelling
TL;DR: In this article, the authors present an efficient algorithm for modelling hydraulic fracturing based on the finite element method. The algorithm is employed for modelling the different coupled non-linear processes that are involved in the problem of hydraulic fracturing.
