Question

Assertion (A): For a ductile material the maximum shear distortion theory is most suitable.
Reason (R): The maximum shear distortion theory of failure assumes that yielding can occur in a general three-dimensional state of stress.

• A. both A and R are true and R is the correct explanation of A
• B. both A and R are true but R is not a correct explanation of A
• C. A is true but R is false
• D. A is false but R is true.

Answer 1

The correct option is B both A and R are true but R is not a correct explanation of A

The maximum shear distortion energy theory of Mises and Henky is in good agreement with various combinations for ductile materials.
