Abstract
In this work three different concepts for a direct application of soil models within a frictional contact description are presented. These concepts can be used in conjunction with all different kinds of contact formulations and solution methods. Additionally, all types of plasticity models can be used within these formulations. The advantage of these concepts is shown exemplary in the modeling process of soil-structure interactions where the Ehlers plasticity model for the continuum is now able to describe the soil behavior at the contact surface. The numerical implementation of the new frictional relations is based on the Mortar method and the numerical investigation of a direct shear test shows the reproduction of the typical stress-strain relation of the soil at the contact surface. The work ends with a critical discussion about the different friction formulations and the application of the Ehlers soil model in a direct shear test.
