Nonlinear finite element modeling of unbound granular materials

For an accurate modeling of the elastic response of granular materials in pavements there are an important number of models described in the literature. This work evaluates three of the most common nonlinear elastic models for unbound granular materials currently used by researchers and practitioners in the pavement engineering field. The nonlinear elastic models of the materials were especially implemented in ABAQUS, a general purpose three dimensional finite element code (3D-FEM) using user defined material subroutines. The 3D-FEM solutions were validated through a set of data collected in the full-scale Canterbury Accelerated Pavement Testing Indoor Facility (CAPTIF). Vertical, transverse, and longitudinal strains were measured at CAPTIF as well as vertical stresses. In general the results obtained from the nonlinear models are considered good for the materials and structures studied in this research. Little difference in the accuracy of the nonlinear models was found under this project.
