Question:medium

Consider the following Assertion (A): A notch increases the tendency for brittle fracture in a material. Reason (R): A notch produces high local stresses, introduces a triaxial tensile state of stress, causes local strain hardening, cracking and magnifies the local strain rate.

Show Hint

Notches increase triaxiality, which suppresses plastic flow and promotes brittle fracture.
