![]() ![]() This dissertation uses the phase field framework to fully couple the martensitic transformation to the variational formulation of brittle fracture.įirstly, the model is parameterized for single crystal zirconia, which experiences tetragonal to monoclinic transformation during crack propagation. This dissertation attempts to provide a mathematical model for crack propagation in transformable zirconia to address the shortage of classical methods. ![]() While the interaction of crack propagation and phase transformation in SMCs has been the subject of several experimental and theoretical studies, mainly at the macroscale, the fundamental understanding of the dynamic interaction of crack propagation and martensitic transformation is poorly understood. Despite outstanding energy dissipation, compared to metallic shape memory materials, SMCs suffer from a sudden brittle fracture. Shape memory ceramics (SMCs) are promising candidates for actuators in extreme environments such as high temperature and corrosive applications. ![]()
