title = "Finite element simulation of the response of No-tension materials",
abstract = "Unbound granular materials that are used at base layer of flexible pavement cannot resist tensile forces. These materials are called no-tension materials. In this paper, a modified strain-energy function was used to describe the constitutive behavior of granular materials to simulate flexible pavement within the finite element framework CAPA3D. The constitutive model was defined such that the positive stresses in principal directions were zero. Comparisons between the no-tension materials and linear elastic materials for different boundary conditions and geometries were presented in this paper. The results of FE analysis show that effect of using no-tension model for base layer on pavement performance is significant. The deformation at top and horizontal strain at the bottom of asphalt concrete layer are higher when the no-tension model is used.",
