Superplastic deformation is considered as a thermo-viscoplastic flow. The deformation and failure of superplastic sheet metals are a result of a combination and interaction process between tensile instability and internal cavity evolution, which are controlled by the rheological parameters (i.e., th

The transient deformation of thin grade 304 stainless steel metal sheets heated by a single pulse of a CO2 laser beam is simulated in this paper. The laser beam is assumed to be line-shaped and the problem is treated as three-dimensional thermo-elastoplastic. The temperature ΓΏeld, deformation patter
