Numerical Analysis on Fracture Splitting of Connecting Rod

Splitting force is the key to the process of fracture splitting connecting rod.In order to get appropriate splitting force,numerical simulation was made by using software MSC.MARC.Jetta car's connecting rod was analyzed.Through analysis,the curve between J integral and splitting force was established.According to the experiential formula of impact toughness and fracture toughness,critical J integral(J_(IC)) was achieved.After getting J_(IC),the splitting force was determined by linear interpolation method and verified by fracture splitting experiment.This kind of numerical simulation method fits splitting force determination for different types and materials connecting rods.
