Hello,
I do have a Femap with NX Nastran model as shown in the attached file. The model consists of two rigid ribs that are in glued connection with a latex sheet (nonlinear elastic). I need to apply 10% pretension to the latex sheet. That is if the distance between two ribs is 10 cm, the length of the skin will be 9 cm. The skin will be stretched and glued to the ribs. I do have ss curves for the sheet with and without pretension.
How to model this pretension in Femap with NX Nastran?
Regards,
Muhammed Sadique
Muhammed Sadique Parancheerivilakkathil Can you share your Nastran model?
use a "virtual" coefficient of thermal linear expansion of the material and apply a temperature change of 1 degree. Calibrate the coefficient or temperature until the desired pretension is reached. And then apply the rest of the existing force factors
