It is the maximum stress that the sheet metal material is subjected to before pulling out. For materials with poisson s ratios ν displaystyle nu close to 0 3 the shear correction factor for a rectangular cross section is approximately. A cross sectional area of the workpiece in2 forces needed to bend sheet metal. Bending the process of cold working metal to achieve a desired profile.

Tensile yield strength x cross sectional area of bend x distance between posts on the die x a constant factor. 0 5 sin α cos α the area of the left center is. Stress is the ratio of applied load to the cross sectional area of an element in tension and isexpressed in pounds per square inch psi. It follows that there is a line or region of zero stress between the.

Where is the area moment of inertia of the cross section is the cross sectional area is the shear modulus is a shear correction factor and is an applied transverse load. When bending a piece of metal one surface of the material stretches in tension while the opposite surface compresses. The area of the left triangle is. A rain gutter is formed by bending up the sides by x inches of a 30 inch wide rectangular metal sheet as shown in the figure.
