Abstract
ABSTRACT In this paper, the response of flexible pavements due to a transient force is analysed by means of a new analytical method. Details of the mathematical derivation, together with a practical example of the implementation are presented. It is shown that the main advantages of the dynamic stiffness matrix approach are its ability to model a whole layer without the need for subdivisions and computational efficiency. Since each element only involves negative exponentials, it surpasses existing methods such as transfer matrix method in terms of stabilization during the calculation process. As a consequence, the size of the modelled structure is only as large as the number of the layers involved, which substantially reduces the computational requirement and hence enables efficient utilization of the method in iterative algorithms for response of flexible pavements.
