Abstract

In this paper we examine some of the essential aspects of modeling pavement structures with three-dimensional finite element analysis. Because three-dimensional problems are so large, special care must be taken to optimize mesh geometry. We describe three issues in mesh construction that have important impacts on overall problem size: (1) mesh refinement, (2) domain extent, and (3) element size transitions. We present an algorithm for computation of the equivalent nodal loads for arbitrary tire prints with arbitrary orientation relative to the mesh. Decoupling the load computation from the problem of mesh construction leads to more efficient meshes and allows efficient resolution for different gear positions.
