I'm working in geotechnics. We are testing "fatigue" response of cyclic loaded sand, where deformation cycles (or strain cycles) of constant amplitude are applied.
I need references to research where deformation cycles (strain controlled fatigue) are observed/measured. Plots of stress / strain curves, where groups of cycles with constant deformation amplitude are applied.
This can be either geotechnics (sand), or other materials. The requirement is that deformation cycles are applied, rather than stress/force.
