Question

Critical resolved shear stress is expressed by the following equation

• A. \(\tau_R = \frac{P}{A} \cos \phi \sin \lambda\)
• B. \(\tau_R = \frac{P}{A} \sin \phi \cos \lambda\)
• C. \(\tau_R = \frac{P}{A} \cos \phi \cos \lambda\)
• D. \(\tau_R = \frac{P}{A} \sin \phi \sin \lambda\)

Hint:

This equation is used in the Schmid law, which describes the relationship between applied stress and slip in crystalline materials.

Answer 1

The Correct Option is A

The critical resolved shear stress (\(\tau_R\)) is calculated based on the applied force, the area of the slip plane, and the angles of the applied force relative to the slip direction and plane.
