between the normal load and the normal deformation of the asperity, the equivalent elasticity
modulus in the joint is deduced by the fitting formula of the joint. Under the condition of the
stress wave propagation in a discrete element, the relation between the normal stiffness and the
tangential stiffness of the joint is obtained. Furthermore, the equivalent Poisson ratio is deduced
by the fitting formula of the joint. To verify the effectiveness of the propose analysis method, this
method is applied to a mechanical structure including joints. The comparison between the
theoretical and experimental results validates the feasibility of the proposed method. The results
presented in this work can be considered as a stepping stone to be used toward the further
research of the joint problem. ©2013 Journal of Mechanical Engineering.
