Hello,

I guess the answer kind of depends on the shape of your sample and how to plan to uniaxially compress your sample :-). At the very least you always have access to the specimen bounding box (specimen max min coordinates) at any point in time [1], so strain is a trivial calc from there. If you use TriaxialStressController, the strains are collected for you [2].

Cheers,

Robert
