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:

Cohesive Dynamics and Brittle Fracture
TL;DR: In this paper, a nonlocal cohesive model for calculating the deformation inside a cracking body is proposed, where a set of physical properties including elastic and softening behavior are assigned to each point in the medium.

FEM Modeling of Fictitious Crack Propagation in Concrete
Walter H. Gerstle,Ming Xie +1 more
TL;DR: Using a mixedmode extension of the Hillerborg fictitious crack model, a practical interface finite element approach is used to model discrete crack propagation in this article, where the fictitious crack tip propagates perpendicular to the maximum tensile principal stress at its tip when the tensile strength is exceeded.

Cohesive elements for thin-walled structures
Ingo Scheider,Wolfgang Brocks +1 more
TL;DR: In this article, a cohesive interface element for ductile tearing of thin structures modelled by plane-stress continuum or shell elements is presented which accounts for thickness reduction, which prevents localisation of plastic deformation in the adjacent continuum elements often inhibiting crack extension and leading to divergence of the numerical simulations.

Symmetric Galerkin boundary element method for quasi-brittle-fracture and frictional contact problems
G. Maier,Giorgio Novati,Z. Cen +2 more
TL;DR: In this paper, the analysis of elastic quasi-brittle structures containing cohesive cracks and contacts with friction is given a unitary formulation in the framework of incremental plasticity, where integral equations for displacements and tractions are enforced by a weighted-residual Galerkin approach so that symmetry is preserved in the key operators.
