Hey,
sorry for the late response.
Something went wrong I uploaded it again. (1mass-oscillator)
Thank you for your example it helped a lot.
This advice also helped a lot.
I think I got this right.The right picture desrcibes the slope of the force-deflection curve.
I didn't understand this part for the non-linear case. How do I need to define my curve for the non-linear case? Same as the linear case?
I have attached my current files. (Nicht_linear_Steifigkeit3.rar)
Thank you
