Impact of stability and surface area on fracture toughness of biological structures
… principles for the trabecular structure. The phase field method, with a novel preconditioner, is subsequently used to characterize the fracture resistance of bone-inspired structures. Specifically, this thesis is divided into two major themes of work: Theme 1: Multigrid methods for large-scale …

Phase-field modeling of fracture: regularization length insensitivity and mixed mode ductile fracture
… time, and occasional impossibility of performing fracture experiments, computational approaches have become instrumental to understand and assess fracture and failure processes in materials and optimize the design of structures. The development of quantitative computational models for predicting …

Topology optimization of multimaterial and multiscale structures beyond elasticity: brittle fracture and ductile plasticity
… subjected to elasticity, plasticity, and fracture under both small and large deformations. The framework embraces both rigorous physics-based methods and general machine learning approaches to predict design performance, which is iteratively improved through gradient-based optimization. …

Application of the Variational Fracture Model to Hydraulic Fracturing in Poroelastic Media
… the use of simple numerical models to describe fracture geometry and propagation. Field tests provide evidence of interaction and merging of multiple fractures, complex fracture geometry and propagation paths. These complicated behaviors suggest that the simple models are incapable of serving as …
