This paper deals with the objective prediction of cracks in concrete structures within the framework of a local constitutive model. To reach this goal, it is necessary to overcome mesh dependency due to softening of concrete. The constitut…

Summary In this contribution, we propose a dynamic gradient damage model as a phase‐field approach for studying brutal fracture phenomena in quasi‐brittle materials under impact‐type loading conditions. Several existing approaches to accou…

In this paper we present a family of gradient-enhanced continuum damage models which can be viewed as a regularization of the variational approach to fracture capable of predicting in a unified framework the onset and space-time dynamic pr…

The IRIS 2012 benchmark [1] was devoted to compare various modelling of impact on reinforced concrete slabs. Its aim was to improve the methods used and to provide guidance to assess the integrity of structures impacted by missiles. During…
