摘要：
The Code of Practice covers method of carrying out tensile creep stress rupture tests on circumferentially notched testpieces. The data obtained can be used for design and lifetime assessment purposes. In this new version, additional information is included to enable the multi-axial creep deformation response of a material to be extracted from the experimental data. However, a detailed knowledge on how the stress redistribution occurs and leads to strain accumulation, requires numerical analysis by a computer in addition to a complete constitutive description of the materials behavior.
