If is the shear modulus of the matrix and V is the volume of the unconstrained hole in the matrix and the elastic energy does not depend on the shape of the precipitate, if so, calculate the elastic strain energy? (Assume the poissons ratio to be 1/3 and Misfit- )

• A. G=4 ²/V
• B. G=4 / ²*V
• C. G=4 ²*V
• D. G=4 ² V
