Advanced Elastomer Fatigue Analysis

Introducing the first commercially available software tool for the fatigue analysis of rubber and elastomers. Developers of rubber materials, components and systems increasingly rely on simulation as a routine means to address design issues. The need for durability simulation is growing exponentially and durability often dominates development agendas. Fatigue analysis solutions from Finite Element Analysis (FEA) have been commercially available for metallic components for many years. These solutions have played a vital role in qualifying design concepts across various industrial sectors. Finally, there is a solution available for elastomers.

fe-safe/Rubber is a:

  • Unique, patented solution for the simulation of fatigue failure in elastomers.
  • Purpose-developed tool for elastomers, possessing a formidable validation.
  • Developed by Endurica, leaders in the development of elastomer technology. 

fe-safe/Rubber at a Glance

Key Facts

  • Integrated into fe-safe’s friendly user-interface to access 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
  • Contains a fatigue characterization scheme for efficiency and ease of application in fe-safe/Rubber. It uses material properties that are accessible through 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.
    • Estimates the energy release rate of a hypothetical defect on each plane as a function of time.
    • Considers the possibility of crack closure for each plane at each instance of time.
    • Identifies the critical plane as the plane that maximizes accumulated damage.
  • 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.
