An orthotropic augmented finite element method (A-FEM) for high-fidelity progressive damage analyses of laminated composites
TL;DR: In this paper, an orthotropic augmented finite element method (A-FEM) was extended to account for the complicated progressive damage processes in laminated composites, which typically develop multiple types of cracking systems including intra-ply matrix/fiber splitting, fiber rupture in tension and/or kinking in compression, and inter-ply delamination.

A stabilized finite element method for enforcing stiff anisotropic cohesive laws using interface elements
TL;DR: In this article, a stabilized finite element method that generalizes Nitsche's method for enforcing stiff anisotropic cohesive laws with different normal and tangential stiffness is presented. But, the method is not suitable for fracture simulation.

Yielding of steel sheets containing slits
TL;DR: In this article, a relation between extent of plastic yielding and external load applied was investigated, and panels containing internal and edge slits were loaded in tension and lengths of plastic zones were measured.
Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TL;DR: 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.

The mathematical theory of equilibrium cracks in brittle fracture
TL;DR: In this paper, the authors present a unified view of the way basic problems in the theory of equilibrium cracks are formulated and discuss the results obtained thereby, and the object of the theory is the study of the equilibrium of solids in the presence of cracks.

Fracture and Size Effect in Concrete and Other Quasibrittle Materials
Zdeněk P. Bažant,Jaime Planas +1 more
TL;DR: In this paper, the authors used the Weibull-type approach to measure the effect of size effect on structural strength of a crack and its size effect in terms of the number of cracks and the size of the cracks.
