What hysterisis are we talking about. ..rate independent


"Systems with rate-independent hysteresis have a persistent memory of the past that remains after the transients have died out.  

The future development of such a system depends on the history of states visited, but does not fade as the events recede into the past

. If an input variable X(t) cycles from X0 to X1 and back again, the output Y(t) may be Y0 initially but a different value Y2 upon return.
 The values of Y(t) depend on the path of values that X(t) passes through but not on the speed at which it traverses the path
.Many authors restrict the term hysteresis to mean only rate-independent "
