The prior objective of the present paper is to predict the formation of desiccation cracks in a mineral liner for landfills. Therefore, a coupled pore water diffusion and stress analysis is made using the finite element method and the numerical program ABAQUS. For this analysis, test results of hydraulic soil relations and tensile behaviour of the investigated cohesive soil are needed. Also the inelastic mechanical properties must be given and implemented in the used numerical model. The present paper shows these test results, the used plasticity model and the geometry, loading and results of the numerical model.
