Abstract

The scatter in the fatigue life of the metallic structures seems to be mainly caused by internal defects of the material (porosity, inclusions as oxide films and carbon layers, grain boundaries, etc.). As discontinuities in geometry, defects cause stress concentration and are therefore [...]

Abstract

Non-local models guaranty that finite element computations on strain softening materials remain sound up to failure from a theoretical and computational [...]

Abstract

Damage models are capable of representing crack initiation and mimicking crack propagation within a continuum framework. Thus, in principle, they do [...]

Abstract

The numerical simulation of complex failure modes of composite materials, such as delamination, can be computationally very demanding, as it requires special elements and/or numerical strategies to characterize damage [...]
