Research Abstract

The present study is concerned with the development of a fracture criterion for the impact fracture of jointed steel plates of bolted joints used in a car body, which contributes to crash simulations by CAE. The object is the parts of lap bolted joints connecting between the suspension frame and the bracket of suspension frame rear mounting in a car. The obtained results suggest that a stress-based fracture criterion may be developed for the impact fracture of jointed steel plates of a lap bolted joint.
