THERMOVISCOELASTIC STRESS ANALYSIS FOR 304 STAINLESS STEEL

Abstract

A constitutive equation applicable to metals is employed which incorporates elasticity, plasticity, and viscoelasticity. Central to this treatment is that all nonlinearities are confined to a quantity known as the “reduced time” so that the final solution technique can utilize linear methods. A 304 stainless steel plate cooled symmetrically from both sides is solved for the transient and residual stresses under different initial temperatures and heat transfer rates.
