Research – Recent collaborations
This page contains some brief articles to preliminary results that I have done in collaborations with colleagues at other institutions.
Simulations of a sheared granular system
This page contains some preliminary results of DEM simulations carried out in collaboration with Ashish Orpe and Arshad Kudrolli at Clark University. We simulate a sheared granular system, and make a quantitative comparison to experimental results.
3D simulations of a conical hopper
In collaboration with Gary Grest at Sandia National Laboratories, I have been analyzing the results of very large scale 3D simulations of granular flow in a conical hopper. We have been able to evaluate some of the classical solutions for conical hoppers, and examine the rheology at the microscopic level.
Simulations of a 2D elastoplastic body
In collaboration with Jim Langer, Frederic Gibou, and Lisa Manning at UC Santa Barbara, I have been carrying out continuum simulations of the STZ model. This page contains some preliminary results of 2D elastoplasticity, that were used to test the code.
STZ simulations of a stretching bar
This page contains results and movies simulating a stretching bar using the STZ theory of amorphous plasticity.
STZ simulations of an expanding cavity
This pages contains results and movies simulating a hole in an infinite material using the STZ theory, to examine the stability of the model.
Visualization of a 3D DLA cluster
A brief article about a movie I made for a talk at the Simple Person's Applied Math Seminar at MIT using simulation data from Jacqueline Yen and Kevin Chu.
Chemical diffusion in a cuboidal cell
This page describes some work I did with Yen-Chen Huang of the Irvine Lab at MIT, doing some simple analysis of the diffusion equation in a rectangular domain.
