Abstract

This paper focuses on the development of a stochastic model of a bolted joint tested experimentally at Sandia National Lab under harmonic excitation and for which the dissipation per cycle and stiffness have been measured at various amplitudes of loading. The applicability of various Iwan-type models for the representation of the measured data is assessed and uncertainty is introduced in one of these models to duplicate the joint to joint variability observed in the test data. The specificities of the uncertainty model and the identification of its parameters are discussed in details.
