Abstract:Void growth in nonlinearly creeping solids under plane-strain conditions is studied in the fifth chapter. Numerical results reveal a rich variety of solutions; in general, void shape is controlled by the strength of the diffusion process relative to the bulk creep process, whereas void size depends critically on the surface energy of the void in relation to the void size and applied load.
