Application Number: JP,2022-072009
Category (FI): G01N3/00@Q,G06F30/23
Stage: PROBLEM TO BE SOLVED: To accurately estimate the relation between initial crack depth and joint strength in a spot welding joint.SOLUTION: A method for estimating spot welding joint performance comprises: a process of deriving the relation between an initial crack depth or a nugget diameter and joint strength, which derives a joint strength limit line and a joint strength estimation line without initial cracks, by the finite element method analysis for a tensile condition of the spot welding j...
