Research work on computational mechanics

My past and on-going research activities involve computational solid mechanics and fluid mechanics.

1. Computational material science

In the past few years, I have established an innovative particle modeling (PM) method that is capable of simulating those problems associated with dynamic fracture mechanics, local damage initiation and propagation, blasting, impact dynamics and thermal effect on material breakage, at both micro and macro scales. The following publications of mine well address PM from its theoretical basis to engineering applications.
