Abstract
This article deals with the objective prediction of damage localization and failure in dynamics within the framework of local constitutive model. A main limitation of such model with respect to failure prediction is that the results can be mesh dependent. In order to overcome this problem, spatial localization limiters have been proposed and widely studied. In this article some limitations of rate-dependent model with respect to localization are discussed. These limitations have given rise to the proposal of bounded rate constitutive model. The approach is illustrated in two cases: – the simulation of failure and perforation of laminated composite structures, – the prediction of failure of metallic structures in finite strain.
