Damage-Resistant Brittle Coatings

Advanced Engineering Materials, 2000
Laminate structures consisting of hard, brittle coatings andsoft, tough substrates are important in a wide variety of engi-neering applications (cutting tools, electronic multilayers, la-minated windscreens), biological structures (teeth and dentalcrowns, shells, bones), and traditional pottery (ceramicglazes).

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 ...

Validating Theories for Brittle Damage

Metallurgical and Materials Transactions A, 2007
Validating simulated predictions of internal damage within armor ceramics is preferable to simply assessing a model’s ability to predict penetration depth, especially if one hopes to perform subsequent “second strike” analyses. We present the results of a study in which crack networks are seeded by using a statistically perturbed strength, the median ...
