Abstract
The classical exponential elastic model and the BB hyperbolic elastic model are used to investigate the effects of nonlinear normal deformation on elastic P-wave normal incidence without the shear deformation considered. A theoretical research is presented on normally incident P-wave transmission across single dry joint with these different nonlinear normal deformation behaviors. Based on the classical and the BB nonlinear models, the different nonlinear displacement discontinuity models are established. Numeric difference resolution and analytic resolution of reflected and transmitted coefficients for normally incident P-wave propagates across single joint with different nonlinear normal deformation behaviors are obtained. Then parametric studies are conducted, in terms of the quantitative ratio of the joint current maximum closure to the joint maximum allowable closure, the joint initial normal stiffness and the incident wave frequency. Comparisons between the results of different nonlinear behaviors are drawn and the conclusions have theoretical meaning.
