Dr. Kuo-Ta Hsieh

Position:Senior: CEM Affiliate

Biography

Dr. Hsieh joined UT-CEM in 2012. His primary research interest has been on parallel multi-physics modeling and simulation such as modeling of high power semiconductor devices, and electromechanical modeling of electromagnetic launching systems.

Prior joining UT-CEM, Dr. Hsieh was an associate director at UT-IAT where he leaded the Material and Computational Analysis Division (MCAD). The focus of the MCAD group is tribology of high-speed electrical contacts, electromagnetic fracture mechanics, electromagnetic effects on conductive fibrous composites, and characterization of material behavior under high strain rate and high heating conditions. The MCAD group has developed a state-of-the-art 3D finite element code, EMAP3D, for solution of coupled electromagnetic-chemical-thermo-mechanical equations and has established and operated a parallel computing facility and Electro-Magnetic Driven Expanding Ring (EMDER) test apparatus. Dr. Hsieh is the author of EMAP3D
