摘要：This paper describes the elastic-plastic-creep analysis of a resistance spot-welded
joint using the finite element method. A solid element model representing the spot-weld has
been considered and is subjected to shear-tension, peel and cross-tension loading. The creep
analysis is studied on a typical geometry that is widely used in experimental laboratories. The
creep behaviour around three points in the spot region and one point remote from the critical
region is studied. A constant temperature of 690 degrees and time duration of up to 100 hours
have been considered. The creep material model is based on the Norton-Bailey law. The
creep stress-strain predictions are compared with simplified notch creep stress-strain
conversion (NCSSC) rule estimates. It was found that the Neuber rule provides conservative
estimates.
