Key Facts
- Friendly user-interface from which to access your finite element results, define duty cycles and specify materials
- Accurate Material Models - highly nonlinear stress strain curves, Mullin's effect, strain crystallization
- Temperature Dependence
- Time Dependence
- Fatigue characterization scheme designed for efficiency and ease of application. fe-safe/Rubber uses material properties that can be directly obtained via readily available experiments
- Pre-populated Materials Database, and add proprietary materials to your own database
- Critical Plane analysis for multiaxial loading:
- a patented critical plane algorithm that considers the individual loading experiences on each potential failure plane of the material
- considers the effects of finite straining on the motions of each potential failure plane
- the energy release rate of a hypothetical defect on each plane is estimated as a function of time
- the possibility of crack closure is considered for each plane at each instance of time
- the critical plane is identified as the plane that maximizes the rate of damage accumulation
- Rainflow counting on a per-plane basis for variable amplitude loading
- fe-safe/Rubber damage accumulation calculations consider the contribution from each peak and valley
fe-safe/Rubber is an add-on module to fe-safe, enabling users to include the effects of complex loading histories, multiaxial fatigue, and other advanced capabilities in fe-safe.
