    The elastic energy stored per unit volume of the material, when its young`s modulus Y is subjected to stress S is
    Given, Young`s modulus =Y, Streaching stress=S, Energy stored per unit volume is, = 1/2 x stress x strian We know that, stress = strain x Y Therefore energy per unit volume will be E = 1/2 x S x S/Y = S / 2Y
