static calculations

Linear static calculation
Performs a linear static analysis. The term linear means that the applied load and the computed response (displacement, internal force) is in a linear relation. 

All the load cases are solved in the analysis. Geometric linearity is an assumption that displacements remain within the limits of the small displacement theory. Through the material linearity, it is assumed that all materials and stiffness characteristics are linear-elastic. The materials assigned to surface elements can be othotropic.

Non-linear static calculation
Performs a nonlinear-elastic static analysis. The term nonlinear means that the applied load and the computed response (displacement, internal force) is not in a linear relation. This can be due to the use of gap, link or non-linear support, truss or spring elements, or taking into account the geometric nonlinearity of truss, beam, rib and shell elements.

AxisVM will perform nonlinear analysis for the selected load cases or combinations and shows a progress dialog.

vibration

Vibration analysis determines the lowest natural frequencies and mode shapes corresponding to the free vibration of an undamped linear structure with no external loads. AxisVM verifies whether the lowest eigenvalues has been determined.
The system mass matrix has a diagonal structure and includes only translational mass components.

dynamic calculations

Dynamic analysis determines time-dependent displacements and forces due to dynamic nodal loads or nodal accelerations.

Dynamic analysis can be performed on models with linear or nonlinear properties.

buckling

Buckling analysis determines the required number of buckling mode shapes and critical load parameters). AxisVM verifies whether the lowest eigenvalues has been determined.
