Consider a single crystal of a hypothetical metal that has the BCC crystal structure. A stress of 50 MPa is applied in the [101] direction of the BCC unit cell. a. Determine the most favourable slip direction for the (011) slip plane of the BCC unit cell. ⟨111⟩ is the family of directions with the highest linear density in the BCC unit cell. b. If τcrss = 27.5 MPa, determine if the single crystal yields. If not, what stress level is required? c. What is the minimum stress at which the BCC single crystal yields?
