Hi everyone,
I need help
1) punch damping matrix
2) For Ground Vibration Test, I need to apply excitation force to the wing. How to model excitation force in Patran/Nastran?
3) how to get Mass matrix from modal analysis, I can get unit mass matrix, I need a mass for each mode for given plate...

Hi Friends,
I have to do SOL 145 with preloads. I have to considere preload for linear and nonlinear deformation of strucutre into consideration for flutter analysis.
Is anybody done this earlier?
Pl. help me,
thanks in advance
