Recent developments on damage modeling and finite element analysis for composite laminates: A review
Pengfei Liu,Jinyang Zheng +1 more
TL;DR: In this paper, a comprehensive review on the general methodologies on the damage constitutive modeling by continuum damage mechanics (CDM), the various failure criteria, the damage evolution law simulating the stiffness degradation, and the finite element implementation of progressive failure analysis in terms of the mechanical response for the variable-stiffness composite laminates arising from the continuous failure.

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.
