Postdoctoral position in the theory of materials
University of California, Santa Barbara
A new post-doctoral position is open for conducting cross-disciplinary basic research in the theory of heterogeneous structural materials. Candidates are sought with strong background in statistics or statistical mechanics, probability theory, and mechanics. A Ph.D. in Mathematics, Physics, or Engineering might be appropriate.
The surface effect on the strain energy release rate of buckling delamination in thin film–substrate systems
Gurtin–Murdoch continuum surface elasticity model is employed to study the buckling
delamination of ultra thin film–substrate system. The effects of surface deformation and
residual stress on the large deflection of ultra thin film are considered in analysis. A
concept of effective bending rigidity (EBR) for ultra thin plate is proposed on the basis of
Gurtin–Murdoch continuum theory and the principle of minimum potential energy. The
governing equations with EBR are formally consistent with the classical plate theory,
