Abstract:

The principal goal of the proposed research is to extend a modeling approach termed the phase-field fracture framework to include the physical behaviors relevant for modeling dynamic ductile fracture and crack evolution. This task will require the inclusion bulk plasticity and fracture energy within the model. Additionally, it is critically important that the development of methodology is carried out in conjunction with novel experiments that allow for detailed observations and modeling of the relevant failure mechanisms. Finally, due to the coupling between the fine scales associated with the fracture process and the coarse scales related to the structural dimensions, further work on the solution of the multi-scale phase-field model is needed in order to make quantitative comparisons between the model and experiments.
