Abstract : Ductile creep rupture is considered and an analysis of a work-hardening plastic material which is subject to creep is made. Under a constant tensile load, the true stress acting on a creep specimen increases and the rate of work-hardening decreases. It is shown that tensile instability develops when the rate of work-hardening becomes equal to the true stress. It is noted that both tensile instability and creep rupture, and compressive instability and column creep buckling are controlled by the current state of workhardening. (Author)
