On stress relaxation, creep, and plastic flow
Recently the author published a time-dependent theory of plasticity including recovery which treats creep strain and plastic strain as mathematically indistinguishable. After presenting a sketch of this theory, we establish the differential equation of low-temperature stress relaxation of the basis of a Mises-type material with kinematic hardening. Then we discuss high-temperature transient creep, steady-state creep, and Norton's rule results as an approximation with Sherby's exponent \(n=5\).
