VSR graduate student Xianlian (Alex) Zou and Professor Jia Lu present a paper at the Iowa Academy of Sciences. Iowa City, IA - April 24, 2004.   Xianlian (Alex) Zhou a VSR Research Assistant presented a paper entitled "Deformable solid modeling using NURBS-based finite element method" at the Iowa Academy of Science in Cedar Falls, IA.   Alex is working towards his PhD in Mechanical and Industrial Engineering under the supervision of Prof. Jia Lu, a VSR faculty member. Deformable modeling techniques have been used in cmputer graphics for decades.  However, most of the existing methods either use overly simplified physical models or don't consider the underlying mechanics at all.  In this paper, we propose a novel pysically based deformable modeling technique which is efficient and yet retains the mathematical rigor of the finite element method.

Professor Jia Lu is a faculty member of the VSR, he joined the College in 2001, he received his  Ph.D. from the University of California-Berkeley in 1999; his M.Eng. from Tsinghua University in 1988 and his B.S. from Beijing Institute of Aeronautics in 1985.  His special Fields of Knowledge are continuum mechanics, finite elasticity, plasticity, finite element methods. His present Research Interests are Theory and finite element formulation for large strain inelasticity; Mechanics of fiber-reinforced membrane; Cellular solids; Modeling of materials with microstructures.
