Metal Forming 2018, 17th International Conference on Metal Forming on 16-19 September in Japan

Metal Forming 2018, 17th International Conference on Metal Forming will take place on 16-19 September in Toyohashi, Japan. Dr. Sergey Stebunov will present article «Prediction of the fracture in cold forging with modified Cockcroft-Latham criterion» and implementation of new QForm subroutine during the event.

A modified Cockcroft-Latham criterion is now available in QForm as a subroutine that shows very good accuracy in tests for different practical cold forming processes. Cold forming technology provides production of net shape parts that require no, or very little, machining. Meanwhile one of the technological problems of cold forming is fracture of the workpiece during production. The use of reliable fracture criteria implemented in QForm metal forming software can help predict possible cracks and find ways to avoid them.Damage factor distribution predicted by modified criterion Cockcroft- Latham-Oh and actual cracks in the cold forged part
