All materials are temperature dependent, but some more than others: metals tend to be crystalline solids and will melt at sufficiently high temperatures; in contrast, crosslinked elastomers are always solids. They can be glassy or rubbery, crystalline or amorphous. When heated to extreme temperatures, they burn rather than melt, producing new substances, usually low molecular weight hydrocarbons (i.e. tarry substances and smoke).
Of course, you do not have to melt or burn a material to see the effects of temperature. In fatigue analysis, we are concerned with stress-strain and crack growth behaviour. These can be temperature dependent for both metals and rubbers. However, while metals have a very high thermal conductivity, rubbers have almost the lowest. Therefore, fatigue analyses involving large temperature gradients are much... READ MORE

Wow – this year has really been one of many firsts for Endurica. We had our first ever Community Conference in April, we started our first sister company – in Europe, and from September 9 – 13, 2024, we presented 4 technical papers – a new Endurica record for one week! The other impressive aspect of this latter feat was that the four presentations were on vastly different topics! I’ll just list the venues and titles and then discuss each one.
International Elastomer Conference 2024, Pittsburgh, PA, USA:
- “Heat Build-Up and Thermal Runaway in a Rotating Bending Experiment”
44th Annual Meeting and Conference of The Tire Society, Akron OH, USA:
- “Coupled Multiphysics Strategy to Monitor the Health of Rubbery Structures Using Endurica Tools”
- “Critical Plane Analysis of Surface-proximal Fields for the Simulation of Mechanochemical Wear”
-
“Models, Materials and the Move Towards Virtual Product Development” READ MORE

We've been shortlisted for R&D Breakthrough of the Year in the Tire Technology International Awards for Innovation and Excellence 2025.
We believe our R&D breakthrough – coupled structural thermal/diffusion simulation for tire oxidation and fatigue – is a game-changer for tire durability testing. It delivers unprecedented simulation accuracy, reducing the need for costly, time-consuming, and destructive prototype testing.
This innovation originated from a collaboration with Akron Rubber Development Laboratory, Inc. and takes into account the combined impacts of mechanical, thermal, and oxidative history, using purpose-developed diffusion and oxidation experiments to obtain the material parameters required for the simulation. The simulation captures not only the mechanical, thermal and oxidative fields but it also tracks the consequent evolution of stiffness and crack growth properties, and their coupled dependencies on stress/strain, temperature and dissolved oxygen concentration.
If you want to know more, Dr. Mahmoud Assaad, our Senior Technical Advisor, will present the fully coupled simulation at the conference during Tire Technology Expo 2025 in Hannover, Germany, on Thursday, March 6, at 9:25 AM.
And if you're attending the exhibition, visit the Endurica team at Booth C218 from March 4–6.
Congratulations to all the award nominees! We look forward to the announcement of the winners at Tire Technology Expo 2025.

Devil in the Details: How to achieve accurate fatigue calculations with Coreform Cubit and Endurica CL | |
Small features on molded rubber parts, such as small radius fillets, mold injection ports, and tire vents, can significantly affect fatigue performance due to their stress-concentrating effects. However, these critical details are often overlooked because of the challenges they pose in meshing.
Accurate fatigue life prediction hinges on precise stress and strain calculations, which are directly tied to mesh quality. Join us for an in-depth discussion on:
- Small features and mesh quality impact on fatigue life.
- Core principles for effective mesh development.
- Tools to simplify and optimize your meshing process.
In this webinar, Dr. Will Mars, founder and President of Endurica, is joined by Greg Vernon, Director of Product at Coreform, and Mark Bauman, Engineering Analyst at Endurica. The team will demonstrate how Coreform Cubit tackles these challenges within Endurica CL. Using an automotive bushing as an example, the team will showcase real-world applications in the rubber industry and provide actionable insights for achieving accurate fatigue predictions with minimal effort.
Don’t miss this opportunity to learn how to master the details that make all the difference in accurate fatigue analysis.

Rubbernecking is an interesting thing that makes us look twice -- this issue we check out what makes stretchy things stretch | |
The Infinite Monkey Cage
What makes stretchy things stretch? Find out as Brian Cox and Robin Ince expand their knowledge of elasticity with Olympian Bryony Page, comedian Jessica Fostekew & experts Dr Anna Ploszajski and Prof James Busfield from Queen Mary University of London. Enjoy this podcast and journey through different applications of elastic materials. Examine, at the molecular level, what happens when we stretch a material and crucially what causes it to return to its original shape. This is especially pertinent to our guest Olympic and British champion trampolinist Bryony Page who has capitalised on elasticity in her 24 year long career. Additionally, hear how scientists sometimes just can’t beat nature; natural rubber and spiders silk are two such cases. Anna Ploszajski takes us through some of the more inventive techniques scientists have engineered to produced more of these natural materials, including genetically engineering goats to be milked for silk.
