NONLINEAR DAMAGE MODEL FOR UNSATURATED COMPACTED SOILS

This paper presents a preliminary attempt to introduce and modify the damage mechanics concepts applicable to metals and rocks as a new theory for modelling collapse deformation of unsaturated compacted soils upon wetting. The model describes the phenomena of collapse deformation as the damage evolution from an initial unsaturated state to a fully saturated state. Water content is the damage factor. Model predictions have been compared satisfactorily with the results of collapse test on a coarse grained soil. (A) For the covering abstract see IRRD 881647.
