We were honored to have Will Mars from Endurica LLC present at the 2026 SIMULIA Americas Users Conference in Novi, Michigan, May 13-14, 2026.

Abstract: 

The oxidation of elastomers in automotive applications significantly reduces fatigue life due to the simultaneous, coupled evolution of material stiffness and strength properties, and crack growth. The new Endurica MP multiphysics fatigue solver offers the ability to capture such effects and their impact on structural response and fatigue performance. Endurica MP features material models for simulating viscoelastic and exothermic self-heating, for rate of oxygen consumption, for stiffness, strength and crack growth property evolution with temperature and oxygen exposure.  It can be coupled with Abaqus structural, thermal and mass diffusion analyses to enable highly realistic simulations of real-world use cases.  It can also be coupled with the Endurica CL, DT and EIE solvers to enable simulation of fatigue performance using infinite life, safe life and damage tolerant analysis workflows.  Validation cases are presented highlighting comparison of simulation results with published experimental studies of aerobic and anaerobic ageing by Gillen and by Ahagon.
