Often it is assumed that the elastic energy/per unit length for an average dislocation is given by: = ^2 Using this assumption, calculate the elastic energy per volume stored in the crystal if the dislocation density increases from 10^10 ^2 to 10^16 ^2. (use the properties of nickel: = 76 and = 0.249 and you can assume = 0.5). What could you do to to release this stored energy
