A Critical Evaluation of Computational Fracture Using a Smeared Crack Approach in MPM
… the material-point method (MPM) as a feasible computational failure approach is performed. The spatial descretization in MPM is defined by a grid of cells that represent space and a set of points that represent the deformable solid. A grid orientation bias in the numerical results is …

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 …

Generalized finite element methods for three-dimensional crack growth simulations
Three-dimensional (3-D) crack growth analysis is crucial for the assessment of structures such as aircrafts, rockets, engines and pressure vessels, which are subjected to extreme loading conditions. The analysis of 3-D arbitrary crack growth using the standard Finite Element Method (FEM) encounters …

A Mesh Objective Algorithm for Modeling Mode-I Cracks Using a Standard Finite Element Formulation
A computationally efficient mesh objective algorithm for modeling mode-I cracks is developed and implemented within a standard finite element formulation. The algorithm applies the crack opening displacements across the standard nodal degrees of freedom that is consistent with formalism of the …

The Role of Local Material Properties in Modeling Fracture Tolerance of the Human Thorax
… the results of dynamic material tests and computational modeling exploring the effects of regional rib mechanical properties on thoracic fracture patterns. Test coupon modeling was used to verify the test setup. These material properties were incorporated into a human body computational …
