Calulating the compression deformation using strain data measured by strain gauge _ material engineering
I'm studying material engineering and conducting some experiment.
The experiment was measuring the strain of long steel bar.
The bar is compressed from left side and deformed shortened.
Using strain ...

What would happen if we applied a stress greater than the yield stress to a rigid-perfectly plastic material?
Say we had a material that was rigid perfectly plastic, with a stress-strain characteristic as shown:
Say that we are drawing this material through two dies, something like this:
What would happen ...
