$Effect of lateral contraction and magnetism on the energy release upon fracture in metals: First-principles computational tensile tests$

Effect of lateral contraction and magnetism on the energy release upon fracture in metals: First-principles computational tensile tests

On many occasions, there is an energy release upon fracture of materials. Taking the {sigma}5 (210) grain boundary in nickel as an example, we have studied the effect of lateral contraction (the Poisson effect) upon stretching and the effect of magnetism on the energy release at the break point, usi...
