The modal analysis allows the determination of the Eigen frequencies of vibration and the evaluation of the associated modal deformations.
This analysis can be launched on a prestressed structure.
The analysis of elastic instabilities beam by beam according to rules' of construction (CM66, Eurocodes...) are not satisfactory to check the stability of complex assemblies. Generalized buckling allows to the determination of the coefficients of performance critical of the loadings (safety margin before the failure) and buckling eigen modes.
The loadings which create great displacements and/or rotations are the incremental analysis object with reactualization of the geometry.
Application ICAB Dynamics/Buckling is a whole of functionalities which are added to software ICAB Force.
