Axi-symmetric analysis of vertically inhomogeneous elastic multilayered systems

Abstract

The importance of accounting for material nonlinearity and anisotropic behaviour in order to improve the resilient models for pavement materials and numerical analysis is presented in this paper. Effects of material inhomogeneity on the pavement primary resilient responses are investigated by way of worked examples of hypothetical three-layer system, which was analyzed by considering homogenous and inhomogeneous material properties in each of the three layers. Effect of a inhomogeneity parameter that is used in the z-dependent exponential model on the resilient responses in the pavement structure was also investigated. This paper reports on the formulation as well as the findings from detailed analyses that were conducted.
