Summary:

Spot Welds are a category of joints used extensively in automotive structures, normally for metals. The fatigue analysis of such spot welds can be evaluated using (a) the Point 2 Point (P2P) method where a beam or bar is used to connect the 2 surfaces being joined, (b) a more modern approach where the 1D element is replaced with an "equivalent" brick element, or (c) a third approach falls somewhere between where a "spider" and circular ring of elements is used to represent the spot weld. In all three cases there is an assumption that the cross section is circular. For some specialist cases such as plastic connectors (Heat Stakes) a new user defined weld is proposed. This paper will describe the approach which is based on the concept that a user generated tensor line (equivalent to the theoretical Force/Moment to stress algorithms built into the P2P approach) can be used along with special S-N curves create for different Heat Stake shapes
