Description
It is recognized in the automotive industry that the effective life of automotive suspension springs is frequently ended by a special yielding phenomenon described in the industry as a load loss or sag, rather than fracture. In the present study the traditional method for characterizing sag behavior of spring steels, i.e., the Bauschinger effect test, is employed to study the sag behavior of several spring steels. Specifically, the effect of hardness on Bauschinger effect and, hence, also on the sag behavior of the spring steels was investigated and the effect of Si on sag behavior has been studied.
