Rubber Material Testing and Fatigue Analysis

Technology Partner

We provide end-to-end testing and simulation solutions for rubber and elastomer components, combining laboratory characterization with advanced fatigue life prediction tools. Our services help manufacturers, designers, and R&D teams improve material performance, durability, and safety while reducing development time and cost.

Rubber and elastomer components are widely used in automotive, aerospace, industrial machinery, and consumer products due to their flexibility, damping characteristics, and resilience. Accurate prediction of their behavior under complex loading and environmental conditions is essential for durability, reliability, and product optimization. Our CAE services provide comprehensive solutions spanning material characterization, modeling, and lifecycle simulation.

Endurica’s characterization services provide precise, physics-informed insights into the fatigue performance of elastomers. Our suite of tests equips you with the critical material parameters needed for accurate simulations and product design optimization. Endurica’s Fatigue Property Mapping service provides all the input you need for your product simulations, helping you understand and predict material behavior under real-world conditions.

While the Hyperelastic Module and the Core Fatigue Module are mandatory for any test, you can build a testing regimen that’s specific to your material to get the physics right.
