True or False? Test your knowledge about Endurica
Endurica is only a software company.
False. While Endurica is perhaps best known for its game-changing fatigue solver software, we also deliver industry-leading testing services, testing instruments, and training. If you need durability for elastomers, we are uniquely positioned to bring you winning capabilities.
Endurica is used by the majority of top rubber product makers.
True. As of the 2021 Rubber News global rankings report, 6 of the top 9 global rubber product makers are using Endurica solutions to characterize and simulate durability.
Endurica invented Critical Plane Analysis.
False, but... Critical Plane Analysis – the technology that gives best accuracy fatigue life predictions under complex multiaxial loading – was originally pioneered by the metals fatigue community. But Endurica does hold the patent on the first Critical Plane Analysis algorithm suitable for elastomers, and we are the world leaders in making the technology available to product developers.
Wohler curve based methods are just as accurate and competitive as Endurica’s Critical Plane / Fracture Mechanics-based method.
False. Wohler curve based methods suffer from many problems that are solved by the Critical Plane Method. 1) they often assume a wrong crack orientation rather than searching for the most damaging scenario, 2) they do not account properly for mode of deformation effects, 3) the testing program required to populate a Wohler curve scales poorly and has poor repeatability.
I don’t need Endurica software if I already have a metal fatigue code (nCode DesignLife, FEMFAT, MSC Fatigue, and fe-safe).
False. Metals and elastomers have completely distinct molecular structures and behaviors. While metals operate at small strain, elastomers tend to operate at large strain. Where metals exhibit linear elasticity, elastomers exhibit nonlinear behavior. Using a metal fatigue code for analyzing elastomer fatigue is like trying to use a car as a boat: you can certainly drive the car into the water, but you end up on the bottom of the lake.
Endurica solvers work with Ansys, Simulia, and Hexagon simulation platforms
True. We maintain software development partnerships with the major finite element software vendors so that we can offer easy to use pre-and post- integrations with Ansys, Abaqus, and MSC/Marc. You can use the Endurica workflows with the finite element code that works for you. We also develop the fe-safe/Rubber plugin.
Everyone knows you can simulate durability.
False. We’re always surprised by the number of people at conferences and trade shows who don’t know that simulating the durability of rubber is even possible. Our tools simulate everything from basic constant amplitude cyclic loading, to variable amplitude, multiaxial loading (up to 6 input channels!), ageing, strain crystallization, ozone attack, cyclic softening, creep crack growth, self-heating, block cycle schedules, residual life. Our multi-threading capabilities mean that large jobs can execute quickly. Our solvers are fast enough to compute damage in real-time for a full finite element model!
Endurica solutions have had significant commercial impact.
True. Endurica was founded in 2008 to reduce rubber product launch cost and risk and we have saved our clients millions of dollars. Endurica’s impact was recognized with the prestigious U.S. Small Business Administration Tibbetts award.
