A single crystal of a metal that has the FCC crystal structure is oriented such that a tensile stress is applied parallel to the [110] direction. The critical resolved shear stress for this material is 1.75 MPa.
1) Calculate the magnitude of applied stress necessary to cause slip to occur on the (111) plane in the (1-10) direction.
2) Calculate the magnitude of applied stress necessary to cause slip to occur on the (111) plane in the (10-1)direction.
3) Which of these two slip systems is the most favourably oriented (which system will see first plastic deformation)?
