Question 1 (a) A sheet-metal component is to be air-bent in a V die. Assuming the flow curve for the metal to be bent is as shown in Figure Q1 (a), show that the force required to cause plastic flow throughout the component is given by the equation: Where = B t W 663 = = = = F= y Bt W the applied force the flow stress of the material the length of the bend the thickness of the material the width of the V die
