- - STRUCTURAL ANALYSES

Analyses Types



Static analysis
- - material/geometrical linearity and non-linearity
Lifetime calculation
- - low cycle fatigue
- - high cycle fatigue
Crack propagation analysis
Structure optimization to

- - maximize lifetime
- - reduce weight
- - reduce cost
Combined problems
- - large assemblies including friction effects
- - complex contact analyses
- - hyperelasticity: rubber components
- - creep

Benefits


Time saving
- - in design phase (less rework, early identification of potential problem)
- - in testing phase (less testing)
Cost saving
- - for needless prototypes (design problems are found earlier)
- - for warranty repairs (since lifetime is analyzed and evaluated)
Competitive advantage
- - you will deliver your product to the market earlier
- - high quality product will increase your competitive advantage

Examples


Design or confi guration change to satisfy requirements for weight, cost, lifetime and structural strength.
Designs comparison pafter the material, manufacturing technology or geometry change, investigating impact on the component strength, lifetime, deformation, etc.
Lifetime calculation based on low cycle fatigue analysis for components with local plastic deformation (number of cycles to crack initiation).
Modeling of the crack propagation inside the structure and the residual lifetime calculation.
