Endurica software release features aging simulation for elastomers

  10/16/2020 - Findlay, OH - The October release of Endurica’s durability simulation software features a new capability to define aging behavior for a material and to calculate the effects of heat exposure history on part durability. According to company founder and president, Dr. Will Mars, “This is a feature that was developed and validated over the last few years in partnership with one of our Tier 1 automotive OEM users for an application where long-term exposure to high temperatures was leading to early part failures.” The aging feature lets users define tabular master curves that define the evolution of key material properties such as stiffness, critical tearing energy and intrinsic strength (i.e., fatigue threshold). The simulation uses the Arrhenius law to calculate the relative aging rate as a function of temperature, and it then integrates to find equivalent exposure time for each element in the finite element model. The simulation captures time-dependent changes in the fatigue crack growth rate law. It can also be coupled to a finite element solver to update stress and strain fields during the solution. Two new outputs for each element are included with the aging feature: age-equivalent time and age-influenced stiffness. As always, the fatigue life distribution can also be output to determine the shortest-lived element. “This is one of our most significant developments to date because aging impacts so many applications,” said Mars. “If there is a big temperature difference, or if their is significant self-heating, and if your part is expected to have long-term endurance, this feature is a real game-changer in terms of your ability to predict durability performance. We see this being used for tires, seals, rubber parts operating near motors, and high pressure/high temperature (HPHT) applications in the oil and gas field. We are very excited to finally launch this capability.” The release also includes a file encryption feature that allows users to share all or part of the simulation input without giving away details like material properties or specific load cases. It also includes a binary-formatted input file that can speed up read/write time by a factor of eight, as well as improvements to the EIE interpolation engine.
