) and a composite based on alumina mixed
with zirconia (ZrO

). This study will be dedicated to the composite and will
be modeled using the Abaqus® software. A speci c approach will be sug-
gested in order to model the microscopic scale, using a strategy as follows.
An algorithm from model generation to mechanical analysis is investigated.
In the eld of ceramics, some mechanical behavior issues are related to
the grain boundaries. In order to describe the interfacial fracture behav-
ior, a cohesive zone law is considered (time-independent). These elements ...
