About this Block
What it does: Calculates the critical buckling load factors and their corresponding mode shapes, for a given Simulation Model and set of Boundary Conditions. Common uses:- Understanding the buckling modes of your model.
- The result of the buckling simulation (‘buckling load factor” property in the block’s properties) is a list of factors by which the model’s load(s) must be multiplied by to reach the critical buckling load for each mode.
- The results are ranked by the intensity of each mode, from high to low.
- You can bound the minimum and maximum eigenvalues, but it will return an error if there are no eigenvalues in that range.
- The loads are assumed to be applied slowly until the model reaches a state of equilibrium (static assumption), and the relationship between loads and displacements is assumed to be linear.
- All inertial and damping forces are neglected.
- Boundary conditions must contain a displacement restraint for at least one node. Otherwise, the model isn’t fixed in space.
- When the calculation is complete, a Head’s Up Display (HUD) will appear that allows you to visualize the block’s results. The block’s visibility must be on to see the results window.
- This is a linear buckling analysis.
- It is recommended to use a Quadratic Geometric order FE Mesh with any analysis to get the most accurate results.
