N2 - Inelastic deformation (combined plastic and creep strain) is known to have significant effects on the tensile and creep deformation behaviour of Type 316H stainless steel. In this work the influence of inelastic strain on the room temperature tensile behaviour of 316H has been examined. Plastic strain was introduced into the material by uniform pre-compression (PC) to 8% plastic strain at room temperature. In addition, creep strain was subsequently introduced into samples by performing uniaxial creep tests on the pre-compressed material. These creep tests were interrupted at various stages of life so that the influence of inelastic damage on the tensile response of the material could be examined. In addition, creep crack growth (CCG) tests have been performed on compact tension C(T) specimens made of 8% pre-compressed material at 550 °C and the results are compared to the existing data on PC material. The results from these tests have been discussed in terms of specimen constraint, initial crack length and loading effects on the CCG behaviour of the PC material.
