With the use of a special contact element by which the frictional contact behavior between leaves is systematically expressed in combination with beam finite elements, the load-deflection hysteresis has been analyzed by a finite element method for two kinds of multi-leaf springs i.e., conventional and progressive types. The load-deflection curve obtained by FEM is neally linear for the conventional type, whereas the curve is highly nonlinear for the progressive one. The numerical results are very close to the experiments in both types of leaf springs. In particular, the proposed method can predict well the hysteresis behavior of the spring. Thus, the proposed FEM analysis using beam elements can be used for designing various types of multi-leaf springs.
