8. Glossary
ductility; ductilité
A material's intrinsic capacity to undergo a certain amount of plastic deformation without breaking (or forming meso-cracks).
germination; nucleation
Mechanism for the appearance of microporosities, either through inclusion fragmentation or inclusion-matrix decohesion.
coalescence; coalescence
Final failure mechanism at microstructural level. Formation of microcracks between pores, leading to complete macroscopic failure of the material.
fracture criterion
Generally decoupled from the material's behavior, a fracture criterion is used to calculate the time at which fracture occurs (either through critical damage or plastic deformation at fracture) as a function of the stress state during the loading...
