The results show that although the effect of Poisson is one of the factors that led to the cracking of soleplate, but not a major factor. Among the causes of the longitudinal cracks in bottom plate, not only the radical force are considered by traditional theory, but also the warping effect of the box and the local trabecular are serious and can not be ignored.
