Lets you determine the lowest (initial) buckling load multipliers and the corresponding mode shapes. AxisVM verifies whether the required number of the lowest eigenvalues has been determined.
The buckling load multiplier ncr = λcr is computed, solving the eigenvalue problem.
λcr is the smallest eigenvalue and the corresponding eigenvector is the buckling mode shape.
The solution technique applied to the associated generalized eigenvalue problem is designed to find the lowest real and positive eigenvalues. It is not suitable to find eigenvalues that are zero or nearly zero. Select load cases or combinations in the tree view. AxisVM will run a linear static analysis before the buckling analysis of the selected load cases.
