Stress-strain data from laboratory tests are used in stress distribution and soil deformation problems. Modulus of elasticity of soils is commonly determined in laboratory from primary loading curves. This paper presents an account of some of the experiments carried out on a silty clay in the unsaturated and undrained state under triaxial conditions and subjected to repeated loading and unloading. The aim is to investigate the stress-strain relation of inelastic soils and the likely variation of the modulus of recompression with the number of cycles and confining pressure. It is concluded from the investigations described that the recompression curves for compacted clays are nonlinear and that the recompression modulus increases during the first few cycles and remains constant thereafter until failure.
