Fatigue Analysis in Marc 2020

Dear,

There is a new feature in Marc 2020, which is fatigue analysis for rubber, in here why we use strain-life instead of stress-life curve? is there a reason for it?

Meanwhile, is there a plan to apply this fatigue analysis feature to other material? like elastic-plastic material.

Thanks in advance!

Because of the nonlinear behavior of rubber, test is easier by applying displacement (strain). It is unlikely to include fatigue analysis for other materials in Marc because MSC has a fatigue code already.
