| Abstract: | The allowable shearing stress of the shearing stress is higher than the allowable shearing stress of the torsion and of the bending strain,when the plastic materials are identical.This phenomenon is caused by the flaws within the matrial. |
| |
| Keywords: | shear torsion transverse bending allowable shearing stress material defect |
