Herein we show that the stress-induced, dislocation-based, elastic hysteric loops of kinking nonlinear elastic solids—polycrystalline cobalt, 10 vol % porous Ti2AlC, and fully dense Ti3SiC2—obey the scalar PreisachMayergoyz phenomenological model because they exhibit wiping out and congruency, two necessary and sufficient tenets of the model. We also demonstrate the power of the model in predicting the response of these materials to complex stress histories, as well as, determining the distributions of the threshold and friction stresses associated with the incipient kink bands—the fundamental microscopic units responsible for kinking nonlinear elasticity.
