Negative stiffness in a link element

[maysamr]

Hello,
TO model a shear key in bridge abutment I have to define a trilinear link in F2 direction, but the third stifness is negative to take acount for the break in shear keys after a defined force limit. Which link type I should use???

I guess I should ask as this " I want to model a trilinear linear link with final permanent deformation that not came back to origion"
What should I do? plz help!!!

Dear Maysam Reshad,

If you really need/want to model the total failure of an element, we suggest you to make use of the 'Deactivation Time/L.F.' feature.
