hi ~ everyone !

I'm studying for the lead-rubber x.

I want to get rid of the degrading in force-displacement graph of Lead-Rubber x
How do I get rid of the degrading?
And, What is there a parameter related to the degrading ?

plz .. T.T

at force-displacement graph of lead rubber bearings How do I get rid of degradation? plz .... set kc 10; #parameter for vertical cavitation set PhiM 0.5; # Maximum damage index set ac 1.0; # strength degradation parameter set cd 0.1; # viscous dampng parameter set sDratio 0.5; # shear distance ratio...

Lead Rubber x sample file analysis

Force-displacement graph in version 2.4.5 and 2.4.4 versions are different.

cause parameter ? command ? why?

Please tell me why whether different
