The thermo-elastoviscoplastic buckling behavior of plates is investiga
ted. The analysis is based on nonlinear kinematic relations and nonlin
ear rate-dependent unified constitutive equations which include both B
onder-Partom's and Walker's material models. A finite element approach
is employed to predict the inelastic buckling behaviour. Numerical ex
amples are given to demonstrate the effects of several parameters, whi
ch include temperature, small initial imperfections, and the thickness
of the plate. Comparisons of buckling responses for the two models, B
odner-Partom's and Walker's, are also presented.
