About the Project

Research Topic

The Material Point Method is a hybrid meshfree numerical method which is commonly used to solve challenging large deformation solid/fluids mechanics problems. In this method, we have a background grid, which is fixed, and a set of particles moving freely over this grid. These particles carry the state of the solid: stresses, strains, temperatures, volume etc. Mathematically, the Material Point Method is a numerical method to solve partial differential equations encountered in solid mechanics (linear momentum equations).

Although it has been used to solve many problems, the method suffers from some fundamental problems. They are:

1.      Energy conservation loss.

2.      Poor accuracy in solving contact problems (for example, the penetration issue).

3.      High computational cost.

This research is in partnership with Dr Phu Nguyen at Department of Civil Engineering, Monash University.

Project Aim

The project aims at developing techniques to mitigate some of the above mentioned issues. Specifically, the student needs to (1) investigate the source of the issues, (2) develop algorithms/methods to solve them, (3) implement in an in-house Material Point Method code and (4) testing the performance of the implemented algorithms.

Eligibility Criteria
