摘要：
The effect of a superimposed hydrostatic tension or compression on the ideal tensile strength of Fe has been computed ab initio using the Projector Augmented Wave method. Interestingly, a superimposed hydrostatic tension increases the ideal tensile strength while hydrostatic compression decreases it. This result can be explained by a simple crystallographic model.
