The damage mechanics of brittle solids in compression

Pure and Applied Geophysics, 1990
The development of microcrack damage in brittle solids in compression is analyzed, using a simple model. The model is developed from recent detailed analysis of the initiation, propagation and linkage of microfractures from pre-existing cracks, voids, or other inhomogeneities.

Dynamic Behavior of Damaged Brittle Solids

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1999
AbstractThe macroscopic dynamic behavior of damaged brittle solids is investigated. Special attention is devoted to the analysis of wave attenuation and dispersion in micro‐cracked solids. Several methods are discussed and numerical examples are presented, to show the dependence of the wave attenuation coefficient and the effective wave velocity in ...

Progressive Damage in Quasi-brittle Solids

2020
We present a model of material degradation relying upon a local damage law supplemented by convex constraints. This results in a damage model with bounded variation that is shown to share the same features of the so-called Thick Level Set approach. Unlike the original model, in the present formulation the level set-based representation is abandoned in ...
