FRACTURE LIMIT
LOAD OF CONE SHAPE PART IN DRAWING PROCESS*
Abstract:
The deformation characters and load status of the blank’s potential fracture zone are analyzed at the moment when blank is approaching to punch corner in drawing process of cone shape part. Based on tension instability theory, the formula for calculating fracture limit load of cone shape part in drawing process is derived. Also, the formula is analyzed and verified by experiment.
Key words:
