I need to model a compressive spring with a hysteresis loopcharacteristic. This is where the force-displacement responseduring compression is different from that when it is released. Thearea constrained by the two curves is the energy lost. I need it todefine a springpack in a railway drawgear assembly. This is theapproximate desired response:

I am using CosmosMotion education edition SP5 and have so far beenunable to generate any form of hysteresis response. I would love tohear from anyone with any suggestions!
