Dynamic fracture of brittle shells in a space-time adaptive isogeometric phase field framework

Abstract

Phase field models for fracture prediction gained popularity as the formulation does not require the specification of ad-hoc criteria and no discontinuities are inserted in the body. This work focuses on dynamic crack evolution of brittle shell structures considering large deformations. The energy contributions from in-plane and out-of-plane deformations are separately split into tensile and compressive components and the resulting coupled system is discretized within the isogeometric analysis framework. The resulting system is solved fully monolithically and adaptive local refinement is used in space and time.
