How can the Poisson's ratio be calculated from stress-strain curves (with images taken at 100 fps)?

I have conducted uniaxial compression tests on my 3D printed samples. Since these are perforated samples, ideally they should have negative (or near zero) Poisson's ratio. However, DIC (digital...

Abnormal distortion on shell element (S4R) under Abaqus explicit compression?

Hi everyone, I have a question that has been bothering me for a month. In Abaqus Explicit, I used shell (S4R) to simulate a compression experiment. I chose 'general contact' with 'all* with...
