SIMULIASimulation
Fatigue of Welds in fe-safe
This course covers simulating the number of cycles till fatigue failures at welds in welded structures. The methods are based on predicting a crack through a certain thickness, in welded structures at the welds (toe, root, throat, etc.; failure mechanisms in welds can be included). Both classification methods (such as BS5400 and BS7608) and structural stress methods (such as the Verity™ module in fe-safe) are included. Examples are provided using FEA output models run in Abaqus, Ansys or Nastran. Not included is temperature-dependent weld fatigue, or weld processes such as friction stir welding or similar. Non-structural joining such as solder is not covered, nor is nonmetallic joining such as adhesive bonding.
