FEMFAT Spot Extension Module: Fatigue Strength Analysis of Spot Welds
It correctly expresses the rigidity of spot welds and SP rivets.
To ensure the structural strength of passenger car and truck cabins, numerous spot welds and punch rivets are required. Each of these joints implies the potential for initial cracks, necessitating particularly reliable methods for fatigue strength analysis. FEMFAT spot provides an evaluation method for accurately simulating the stiffness and durability strength of thin sheet metal components composed of spot welds. FEMFAT spot offers two different approaches: ◆ A method using element stresses from shell elements ◆ A method using element forces from connection elements (JSAE method) *For more details, please download the PDF or contact us.
