Thermoelastoplastic Analysis of a Stainless Steel Plate Considering Phase Transformations

A quasistatic thermoelastoplastic analysis is given for the response of a traction-free plate subject to surface heating. The formulation incorporates temperature-induced phase changes which model experimentally obtained data for X22 CrMoV 12 1 stainless steel. The plate is discretized into layers, with material properties considered homogeneous within each layer. An incremental, iterative approach based upon Kirchhoff bending theory is employed to obtain an approximate solution to the problem. Numerical results illustrate the effects of phase transformations and temperature sensitivity of the material properties upon the transient and residual stress distributions.
