Biography
Dr. Wu is currently Associate Professor in the School of Mechanical and Aerospace Engineering, and was formerly a faculty member in the Department of Engineering Mechanics at the University of Nebraska-Lincoln, USA. He received his B.Sc. degree from University College London in 1985, and his S.M. and Ph.D. degrees from the Massachusetts Institute of Technology in 1987 and 1990, respectively. His research interests include soft matter mechanics, defect and fracture mechanics, inverse problems, and composite materials. His research has been funded by the Agency for Science, Technology and Research, and by the National Science Foundation, the Office of Naval Research and the Army Research Office in the USA.

Research
  • Interest:
    Soft matter mechanics, nonlinear elastography, composite materials, crystalline defects, failure mechanics
  • Projects:
    Poynting and inverse Poynting effects in cylindrical composites
    The change in length of a cylindrical multilayered composite bar under pure torsion is shown to be dependent on the second- and third-order elastic constants and the layer thicknesses. Further, the twist of a cylindrical bar under combined axial-torsional loading is a function of the axial loading, and this nonlinear phenomenon may be termed the “inverse Poynting” effect.

    Nonlinear mechanics of biogels
    The stresses and displacements in composite gels subjected to axial, torsion, shear and dilatational loadings are determined using second-order elasticity. The development of normal and out-of-plane shear stresses in a soft solid subjected to generalized simple shear is investigated in terms of the geometric and elastic parameters. The results have important implications for regenerative medicine and drug delivery applications.

    Disclinations, dislocations, cracks and surface effects in polycrystalline materials
    Disclinations (rotational crystalline defects), dislocations (linear crystalline defects) and cracks are often responsible for the failure of polycrystalline materials. The research focuses on the study of the stresses around such defects, and also on the surface effects which might be important in nanocrystalline materials due to the large surface to volume ratio.
