stress-controlled loading
stress-controlled loading
(OP)
Hello,
i would like to simulate a tensile test under stress-controlled loading and to compare numerical results to experiments.
Experimentally, i have imposed the form of this cycle (figure):
loading sequence: load up 4kN, 1mm/min
unloading sequence: unloading with a displacement -1mm/min
so my unloading sequence is not under load control (it is impossible with our tensile machine).
How can i simulate this test under stress-controlled loading?what is the form of my loading-unloading sequence?
Thank you

RE: stress-controlled loading
Is there significant area change (eg necking) under load ? if not then load and stress are interchangeable.
Is this a "fitting" or a "panel" specimen ? ie are there secondary terms that need to be considered (ie if panel then poisson).
another day in paradise, or is paradise one day closer ?
