| Abstract: | The experimental technique of joint closure and the measurement method of initial aperture of joints are introduced in this paper.The mechanism of nonlinear unrecoverable deformation during joint closure is inquired into.Thecharacteristics of composite topography and closure behaviour of joints on different contact states are studied.The relation equation of normal load-normal deformation containing the topographic parameters of composite profiles and dimensionless initial aperture is obtained. |
