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
Static Structural (FEA) | Practical Industry Applications
Common static structural requests and/or projects from business partners (including, but not limited to):
Once Through Steam Generator
