| LSTC | Ph. D. C.T. Wu (吳政唐博士) Senior Scientist | | Dr. C. T. Wu jointed LSTC in 2001. His specialty is in the area of computational mechanics and applied mathematics. At LSTC, Dr. Wu’s research is emphasized on the methodology development and numerical error analysis of advanced finite element and meshfree methods for solid and structural simulations. His interests of applications cover large deformation, material failure, composite/immersed structures, multi-scale/unit cells, multi-physics and constrained problems. Dr. Wu has authored or co-authored over 100 articles in various international referred journals, book chapters and conference proceedings. He also services as the member of editorial board for two journals and is a member of USACM and IACM since 1999. |
