FragData—High-fidelity Data on Dynamic Fragmentation of Brittle Materials

Nitin Daphalapurkar, PhD, Assistant Research Professor, Mechanical Engineering, Johns Hopkins University

Professors Daphalapurkar and Graham-Brady of Hopkins Extreme Materials Institute are constructing a massive dynamic-fragmentation database (FragData) for materials undergoing failure in critical applications. They envisage FragData would help expand understanding on the mechanics of failure processes associated with, for example, disruption of asteroids, fragmentation of protection materials under impact, and debris formation of construction materials under catastrophic loading. The idea is to have the database openly accessible, have tools to carry out in situ analysis, and have the database serve as a central platform for other researchers to interpret the massive data from state-of-the-art particle-based and finite-element-based simulation techniques.
