Question

Consider a single crystal of some hypothetical metal that has the BCC crystal structure and is oriented such that a tensile stress is applied along a [121] direction. If slip occurs on a (101) plane and in a $[\overline{1} 11]$ direction, compute the stress at which the crystal yields if its critical resolved shear stress is $2.4 \mathrm{MPa}$

Step 1

The Schmid factor is given by the dot product of the slip direction and the normal to the slip plane, divided by the product of their magnitudes. For the given slip system, the slip direction is $[\overline{1} 11]$ and the normal to the slip plane is $[101]$. Show more…
