GATE 2019 : Calculated the associated stored energy.

Cold working of iron leads to increase in dislocation density from 10^10 to 10^15 m^-2. The associated stored energy (in MJ. m^-3, rounded off to one decimal place) is _________. Given: Shear modulus of iron = 82 GPa, Burger’s vector, b =a0/2[111]. a0=0.2856 nm.
