ELASTIC-PLASTIC WORK-HARDENING MODEL FOR SOFT CLAYS

A variant of Dimaggio-Sandler model for work-hardening soils is proposed. Incremental theory of plasticity is used to set up constitutive relations. Stress-strain relations for the model are described in terms of compression index, the swelling index, the cohesion and the angle of interval friction of soil. Finite element method is applied to develop computer programs to solve the dimensional and axisymmetric problems with arbitrary boundary conditions. Results of laboratory tests on Grundite clay are compared with predictions from the finite element analysis using the proposed model. The close agreement between experimental data and analytical results suggests that the constitutive model is applicable to the class of materials tested. (Author/TRRL)
