    Hi,

    Try with Type 13 spring in Radioss. This beam type spring property works as a beam element with six independent modes of deformation. This spring accounts for non-linear stiffness, damping and different unloading. Deformation, force and energy-based failure criteria are available.

    For more details and input parameters, please refer our help menu.

    Also, please watch the webinar on Type 13 spring : https://altair-2.wistia.com/medias/bsf1x7k3rd

    hi,

        is it possible to use Type 8 spring to simulate the cbush element?

    Hi,

    Type 8 spring property works with six independent modes of deformation and it is a zero length spring. This spring accounts for non-linear stiffness, damping and different unloading. Deformation, force and energy based failure criteria are available.

    Please refer this webinar for Type 8 spring: https://altair-2.wistia.com/medias/vcidbz42ah

    Do you mean that both Type 8 and Type 13 can solve my problem?
