Even in science, there are things that are difficult to measure with 100-percent accuracy. Passion, for instance. Heart, for another.
But it doesn't take advanced instrumentation or software to know for sure that Will Mars possesses both in abundance. And when it comes to the impact he has on the tire industry, there is no denying the correlation. READ MORE

Heat Build-Up and Rolling Resistance Analysis of a Solid Tire: Experimental Observation and Numerical Simulation with Thermo-Mechanical Coupling Method
by Hong He,Jinming Liu,Yaru Zhang,Xue Han,William V. Mars,Liqun Zhang, and Fanzhu Li
The hysteresis of rubber materials due to deformation and viscoelasticity is the main reason for the heat build-up (HBU) and rolling resistance (RR) of the rolling tire. It is important to realize the high precision prediction of HBU and RR of tire for the optimal design of high-performance fuel-saving tire. In this work, a thermo-mechanical coupling method based on Endurica and Abaqus co-simulation was used to predict the steady-state temperature distribution and RR of three finite element models (Lagrangian–Eulerian model, Lagrangian model, and Plane Strain model) of the solid tires under different loads and rotating speeds.

Endurica's first company picnic and canoe trip celebrated our 14th year in business. Just one canoe capsized during the 7+ mile trek down Ohio's Black Fork Mohican River. In the photo at right, the Endurica team includes (back row, from left) Yang Chen, Intern; Joe Suter, Financial Manager; Mark Bauman, Engineering Analyst; Ethan Steiner, Intern; Will Mars, President and Founder; (front row, from left) Kerrigan Dick, Intern; Pauline Glaza, Marketing Manager. Missing from the team phot are Jesse Suter, Development Manager and Abdullah Amin, Project Engineer. |

By keeping tearing energy at all times below the intrinsic strength, a developer can assure indefinite life with minimum effort. Several examples will be presented, including:
- a grommet sizing application
- a tire belt compounding application
- a squeeze pump hose
Join us to view how Endurica computes the fraction of loading reserve (ie safety factor) relative to the experimentally determined intrinsic strength.

Rubbernecking at Endurica: an interesting thing that makes us look twice
Rubber chemists use the rheometer curve to check a rubber compound's cure behavior. The specimens look a little bit like an oreo cookie. Check out this fun "kitchen chemistry" activity. For about $6 in materials, you can make a 3D printed "rheometer/oreometer". Check it out at: On Oreology, the fracture and flow of "milk's favorite cookie."
