Engineering Software Programming in Contact and Continuum Mechanics, Boundary Element Modeling , Finite Element Modeling , Nano / Macro Tribology in Information Storage Systems, Computer Graphics

11/01~ present

Developed 3-D numerical models to simulate the thermo-magneto-mechanical performance of the head / media interface in HAMR (Heat Assisted Magnetic Recording). A boundary element based code is developed in FORTRAN and benchmarked with ANSYS / Mechanical.

09/98~ 06/01

Developed a 3-D numerical model to simulate the contact of layered elastic/plastic solids with random rough surfaces. A boundary element based code is developed in FORTRAN.

01/01~ 06/01 Performed MPI-based parallel programming on a shared memory supercomputer to accelerate the computation of the 3-D contact model; designed a Graphical User Interface with C++; built a Vector Field Visualization class for VTK to render the 3D stress and strain vector fields
01/99~ 12/99 Measured surface roughness of magnetic tape and cartridge components with AFM, WYKO, and Tencor; performed numerical simulation and experimental verification on the tribological behavior between the tape and the bearing surfaces of the cartridge in Micro / Nano scale
09/97~ 09/98 Developed a 3-D numerical model for the contact of surfaces with multi-modal roughness distributions. The model was applied in surface finishing and coating deposition processes to predict the bimodal distribution effect
