Abstract
This paper presents a numerical framework for the
simulation of dynamic fracture of heterogeneous material. It consists in a
multibody approach based both on the concept of Frictional Cohesive Zone
Model and on NonSmooth Contact Dynamics. The heterogeneities of the material
are taken into account using a multiscale method. The microscopic scale
corresponds to the scale of heterogeneities. The macroscopic scale
corresponds to the structure where gradients of properties will be invoked.
The ability of the framework is illustrated by the fracture of hydrided
Zircaloy-4, constituting nuclear cladding tube, under transient loading.
