Abstract

In this communication, we propose to discuss the interest of developing isogeometric space-time approaches for the numerical description of fracture in the context of gradient damage models. We focus here on elastic brittle fracture that requires special algorithmic treatments due to the non-convexity of the minimization problem. We discuss the benefits that can be expected from such an approach with simple application examples. We also illustrate the interest of a generic implementation of space-time isogeometric analysis in a natively multifields and multigrids software architecture for the development of more complex physics in fracture propagation problems (thermomechanics, etc).
