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:

Fracture Mechanics of Bond in Reinforced Concrete
TL;DR: In this article, a nonlinear, discrete crack, interface and finite element approach was used to predict the bond-slip behavior of a reinforced concrete reinforcement bar embedded in concrete.
Journal ArticleDOI
Simulating DCB, ENF and MMB experiments using shell elements and a cohesive zone model
TL;DR: In this paper, a delamination model for shell elements is presented, which consists of an adhesive penalty contact formulation for initially tying shells together and a cohesive zone model for degrading the adhesive forces.

Effects of Strain Rate on Tensile Behavior of Reactive Powder Concrete
TL;DR: In this article, the effects of strain rates on tensile behaviors of reactive powder concrete (RPC) specimens subjected to rapid loading were investigated and a rate-dependent bridging law expressing the relation between tensile stress and crack opening was proposed.
Journal ArticleDOI
Numerical investigation of fracture spacing and sequencing effects on multiple hydraulic fracture interference and coalescence in brittle and ductile reservoir rocks
TL;DR: In this paper, a fully coupled hydraulic fracture propagation model based on the Extended Finite Element Method (XFEM), Cohesive Zone Method (CZM) and Mohr-Coulomb theory of plasticity is presented, to investigate the interference and coalescence of fluid-driven hydraulic fractures that initiated from horizontal wells.
