Finite-element structural analysis fundamentals

The finite-element method represents load paths, stress, deformation and stability in components and assemblies.

Applications

Aerospace · Off-highway · Rail

Model setup

Components are represented with appropriate solid, shell, beam or contact elements. Material model, joints, supports and load introduction define the load path.

Static assessment

Static analyses evaluate stress, deformation, contact force and margins under defined load combinations.

  • Self-weight and operating loads
  • Pressure and distributed loads
  • Bolted and welded joints
  • Linear and nonlinear contact

Stability and model checks

Thin-walled structures may require eigenvalue or nonlinear buckling analysis. Mesh, boundary conditions and singularities are reviewed in relation to the design decision.
