a. reaches the value of yield point
b. reaches the value of strain energy stored per unit volume at yield point
c. reaches the value of strain energy stored per unit volume at elastic limit
d. exceeds total strain energy caused by uniaxial stress at elastic point

ANSWER: reaches the value of strain energy stored per unit volume at elastic limit

    As strain energy or resilience is calculated under the elastic limits hence the yield comes under elastic limit.

    B is right option
    It should be at yield point

    - Different theories of failures are developed depending upon physical behavior of materials.

    - Maximum strain energy theory is also called as Beltrami and Haigh theory.

    - According to maximum strain energy theory, failure of material due to complex stresses occurs when total stored energy per unit volume at a point reaches the value of strain energy stored per unit volume at elastic limit.

    - The energy stored by a system undergoing deformation is called as strain energy.
