Respected ABAQUS users, I actually performed shear fracture test of the joint formed by curing a binder between two plates with varying composition of binder containing metal nanoparticles. In doing a test I get some binder composition in which the stress-strain curve is almost linear but very slightly curved. It seems that may be there is lack of yielding or my be there is a yielding but its very unclear and difficult to find. I need to know how to find yield point inn such a case to develop input data of plastic yielding?
Secondly if the material is more britlle with very little yielding but it have fatigue life experimentally during the cyclic loading experiment I performed. So how to simulate it using abaqus becasue it has no yield strain and yield stress properly defined or may not have these value instead it have value of fracture strength. How to get hysteresis loop of such a problem or which input data will be supported by ABAQUS to perform hyteresis of brittle material during cyclic loading as just for ductile materials we use plasticity data? The out put data is plotted here for stress and strain curve in SI units.
Thanks for cooperation
