About me

With 4 years undergradute study in fluid mechanics, heat transfer, thermal dynamics, power generator principle and 4 years graduate study in finite element analysis, fracture/failure analysis, nonlinear elasticity, plasticity, material structural optimization, I have gained solid knowledge and experience in mechanical engineering and more importantly the ability of learning and solving problems. My research involved large amount of programming with: C++, Matlab, Python, Bash, Fortran and MPI/OpenMP. I'm experienced in developing large generic parallelized FEM code from scratch. I am now seeking for internship and job (graduating in 2016) related to continuum scale computational solid mechanics.


Polyurea coating cavitation failure analysis

Cavitation failure and erosion is observed on polyurea coated turbine blades which is expected to be resistant to the bubble collapse caused cyclic shock waves. A more comprehensive mechanical analysis of polyurea coating under extremed conditions is performed to develop an optimized molecular structure of polyurea. This project involved a costumizable and reliable finite element analysis platform, which is a more than 10000 lines code, and a thorough study of the foundamental elasticity theory to develop a better constitutive model for polyurea.

Genetic algorithm based quadrature method for explicit XFEM

As eXtended FEM is deeply understood and widely applied, its quadrature difficulty becomes a major limitation of being adopted in large systems. A robust and efficient quadrature rule searching method based on GA is created and tested to be fast and accurate in explicit simulations where integration points calculation .
