Hysteresis is a special type of behavior encountered in physical systems: in a hysteretic system, when the input is periodic and varies slowly, the steady-state part of the output- versus-input graph becomes a loop called hysteresis loop . In the presence of perturbed in- puts, this hysteresis loop presents small lobes called minor loops that are located inside a larger curve called major loop. The study of minor loops is becoming increasingly popular since it leads to a quantification of the loss of energy. The aim of the present paper is to give an explicit analytic expression of the minor loops of the LuGre and the Dahl models of dynamic dry friction.
