FE-Simulation of fillet Rolling and Fatigue life Calculation based on Fracture Mechanics Concepts

摘要

Fillet rolling is a method which significantly improves the fati- gue strength of members. Residual stresses induced stresses induced in the surface layer during the fillet rolling process are able to retard or prevent crack propagation. For fatigue strength prediction of fillet rolled notched members a Fracture mechanics based concept is described. It consists of three Parts: Finite element simulations of the fillet rolling process to calculate The residual stresses.
