Abstract

The paper presents closed-form analytical solution to the plane-strain problem of stress relaxation in a bended plate with tension-compression asymmetry (TCA) in viscous properties. Reversible and irreversible strains are assumed to be finite. We utilize a linear viscous model with equivalent stress that is piecewise linear function of the principal stresses with TCA parameter. The specific features of the solution are discussed.

Keywords
