The yield stress is a piecewise linear function of pressure.
In tension (negative values of pressure), such materials have little tensile strength and this is modeled by dropping the yield stress rapidly to zero as pressure goes negative to give a realistic value for the limited tensile strength.
Note: You can use up to 10 pressure-yield points to define the material strength curve.
This property can only be applied to solid bodies.
