Moving window techniques to model shock wave propagation using the concurrent atomistic-continuum method
Alexander S. Davis, Jeffrey T. Lloyd, Vinamra Agrawal
Atomistic methods have successfully modeled different aspects of shock wave propagation in mate-rials over the past several decades, but they suffer from limitations which restrict…
Graph neural networks for simulating crack coalescence and propagation in brittle materials
Roberto Perera, Davide Guzzetti, Vinamra Agrawal
High-fidelity fracture mechanics simulations of multiple microcracks interaction via physics-based models quickly become computationally expensive as the number of microcracks incr…
Block structured adaptive mesh refinement and strong form elasticity approach to phase field fracture with applications to delamination, crack branching and crack deflection
Vinamra Agrawal, Brandon Runnels
Fracture is a ubiquitous phenomenon in most composite engineering structures, and is often the responsible mechanism for catastrophic failure. Over the past several decades, many a…
Optimized and autonomous machine learning framework for characterizing pores, particles, grains and grain boundaries in microstructural images
Roberto Perera, Davide Guzzetti, Vinamra Agrawal
Additively manufactured metals exhibit heterogeneous microstructure which dictates their material and failure properties. Experimental microstructural characterization techniques g…
