Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.

Question

8) An FCC crystal is subjected to a tensile stress. This stress is applied in a direction that forms an angle of 28.1° with the slip plane of the crystal, and an angle of 62.4° with the slip direction respectively within the crystal. If a tensile stress of 0.80MPa is applied:

a) Calculate the Resolved Shear Stress for the Crystal

b) If the material's Critical Resolved Shear Stress is 0.73MPa and a Safety Factor of 2 is applied to that stress, is your Resolved Shear Stress from "Part a" considered "safe" with respect to your Working Stress?

(HINT: Safety Factors can be applied to Shear Stresses the same way they are applied to Normal Stresses)
