Rubber (hyperelastic) part failure estimation
Rubber (hyperelastic) part failure estimation
(OP)
Hi everyone!
I was wondering if there is a simple way to estimate rubber part is exposed to failure or not.
For example if I have some hyperelasticity model coefficients ( Marlow, Yeoh, Ogden or any else) and I've finished FE-calculation of structure including rubber parts, how can I check if it safe case for my design? I mean for metals we can simply compare calculated stress with material yield stress (as an first estimation), or check endurance limit; is there similar approaches for hyperelastic components?
Best regards

RE: Rubber (hyperelastic) part failure estimation
This article's authors refer to hyperelastic material fail under tension or shear strain. Is it correct to state that there is no fail of rubber under compression?
