Document:
Measuring and Modeling the Fatigue Performance of Elastomers for Applications with Complex Loading Requirements. Shows how the fe-safe/Rubber fatigue analysis software has been applied to the case of an elastomeric annular blow out preventer.
Choosing the right material in a rubber bushing operating under variable amplitude loading. The presentation shows how the fe-safe/Rubber fatigue analysis software, which is based on Endurica fatigue solver technology, has been applied to the case of a rubber bushing.
Critical Plane Analysis of Tension, Shear, and Compression Example calculations showing the application of Critical Plane Analysis to commonly encountered modes of deformation. Critical Plane Analysis predicts both the life and the orientation of the plane on which cracks first initiate.
Why do we call it the Pure Shear test? This experiment is useful for both hyperelastic and fracture mechanical characterizations of rubber. We explain the nomenclature.
Comparing Pure Shear and Simple Shear The spin and rate of deformation tensors for these two common testing scenarios are computed and compared.
Characterizing Rubber’s Fatigue Design Envelope How to efficiently characterize rubber’s fatigue design envelope, based on measurements of fatigue crack growth rate under both relaxing and nonrelaxing conditions. Presented at the Spring 2012 meeting of the ACS Rubber Division.
Identifying the damaging events in a multiaxial duty cycle Keynote lecture given at ECCMR 2009 reviewing state of the art in fatigue life prediction.
The Endurica fatigue solver is used to estimate the damaging effects of a multiaxial, variable amplitude mission profile on Natural Rubber (NR), and Styrene Butadiene Rubber (SBR) compounds.
