Good evening
My name is alessandro, I'm a graduate student of civil engineering.
the thesis I'm dealing with, it concerns the calibration of a model, using abaqus software.
the purpose is to obtain a force-setting curve, regarding a beam-pilaster node, at the end of the beam, of which I attach an attachment-1.
to model concrete, I am using a theory called cdpm "concrete plastic damage model", in which the decrease of stiffness of concrete, due to cracking, is given by two parameters of damage, dc (Annex-3) and dt (Annex-4).
As for monotonous tests, I have no problem, for cyclic tests, however, it turns out that stiffness remains constant; in Annex-2, the yellow curves concern the model, the celestial experimental curve. my doubt is that for monotonous, there is the degradation of stiffness, so the parameters implemented in abaqus, were put correctly. I don't understand the problem with cyclics.
Thank you.
