When the Elastic tab is selected, the Release Definition dialog displays the following.
To define an elastic release:
Elasticity coefficients are available only when the elastic releases option or the unilateral release option is selected. Elasticity coefficient values for linear releases are specified in the following units:
Kx, Ky, Kz = force / (length * length)
Hx = (force * length) / (angle _measurement * length).
