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:

Numerical Procedure for Dynamic Simulation of Discrete Fractures Due to Blasting
M. R. Saharan,Hani S. Mitri +1 more
TL;DR: In this article, a generic nonlinear, dynamic modeling technique was proposed to simulate discrete rock fractures due to blasting using the finite element method. But the authors did not consider the effect of the dynamic load on the fracture initiation and growth.

Crack extension resistance based on the cohesive force in concrete
Hans W. Reinhardt,Shilang Xu +1 more
TL;DR: In this article, the crack extension resistance associated with the cohesive force on the fictitious crack is investigated in detail for standard three-point bending notched beams, and numerical computations have been carried out using a commercial computer program for nonlinear finite element analysis of reinforced concrete structures.

Application of hydrogen influenced cohesive laws in the prediction of hydrogen induced stress cracking in 25%Cr duplex stainless steel
TL;DR: In this paper, the suitability of the linear and polynomial cohesive laws in predicting hydrogen induced stress cracking was investigated by applying models of U and V-notched tensile specimens representing a 25%Cr duplex stainless steel component submerged in sea water under cathodic protection.

Cohesive cracks versus nonlocal models: Closing the gap
TL;DR: Using a uniaxial formulation and a Rankine-type model, this paper showed that the cohesive crack may be obtained as a particular case of a fully nonlocal formulation.
