Static Structural Analysis

Static structural analyses permit the prediction of deflection, temperature, strain, and stress distributions within a component and/or assembly.

Verification Cases & Static Structural Analyses

A static structural analysis determines the effect of steady (or static) loading conditions on a structure, while omitting inertia and damping effects, such as those caused by time varying loads.

Static structural measurements is the most common analysis performed for verification and/or validation, but does not indicate that they are always simple in nature.
In fact, these have evolved to include complex interactions within the analysis (contacts, joints, composites) to linking with other physics (fluid-structure, electromagnetic-structure).
Significant performance insight into a component and/or assembly can be obtained from a static simulation
