No Compression or No Tension

You can obtain the modified elastic behavior by first solving for the principal stresses assuming linear elasticity and then setting the appropriate principal stress values to zero.

In addition, set the associated stiffness matrix components to zero. These models are not history dependent: the directions in which the principal stresses are set to zero are recalculated at every iteration. No compression and no tension definitions modify only the elastic response of the material.

Parameters
