Non linear Buckling with FEM approach
Buckling analysis assesses the stability characteristics of a structure. An accurate solution to a buckling problem requires more efforts than just following a numerical procedure, there are a number of factors to consider before a buckling solution can be accepted … Continue reading
Random Vibration Analysis – Nastran SOL 111
Introduction Random vibration is motion which is non-deterministic, meaning that future behavior cannot be precisely predicted, and it is a characteristic of the input or excitation. To specific a random vibration is usually is used the ASD (acceleration spectral … Continue reading
Linear Buckling Analysis – SOL 105
Theoretical Background Buckling analysis assesses the stability characteristics dictating the integrity limit of a structure. Let us start with a linear equation of motion for a preloaded structure: where M,C, K and Kd are mass, viscous damping, material and differential stiffness … Continue reading
