Nonlinear Cbush

Hi,

I'm trying to implement a nonlinear spring constant with a polynominal approach. For Example; c= 165x^3-115x^2+57x+4.

Is this possible? Also in Sol103

Thanks
Michael

Re: Nonlinear Cbush

Nonlinear spring stiffness is defined on PBUSHT using the KN flag. The actual stiffness data is defined on TABLEDi entries, so you would need to discretize your function to generate the data.

Per PBUSHT remarks 5-7, this is only supported in SOL's 106, 129 and 601
