Notes for Spall and Fragmentation

Recently Henry talked about software that could be used to simulate explosions and introduced CartaBlanca. Luming asked whether anyone had used the software, how good it was, and whether one needed Java to implement models into CartaBlanca.

As far as I understand, CartaBlanca is the offshoot of Brian (Bucky) Kashiawa's CFDLib code and contains an implementation of Debra Sulsky's version of MPM. Our group had worked closely with Bucky in early stages of the development of the Uintah code at C-SAFE. Bucky's fluid-structure interaction ideas form the basis of our code though we have moved away from Sulsky's version of MPM.

An Australian Research Council funded PhD Scholarship is available in the Department of Civil Engineering at Monash University in Australia in the area of computational mechanics. The objective of this project is to develop a multi-scale bifurcation-based decohesion model within the framework of the Material Point Method (MPM), one of the meshfree methods, for simulating glass fragmentation under blast loading. The proposed multi-scale decohesion model will be calibrated by combining molecular dynamics and continuum mechanics approaches, and the simulation results will be verified by available experimental data.
