Strain Model

Soils have nonlinear stiffness and develops irrecoverable strains even at very small strain levels. Accurate modeling of stress-strain behaviour at various strain levels is very important for predicting the deformation of soils. Some existing stress-strain models are reviewed and evaluated firstly. And then a new simple non-linear stress-strain model is proposed. Four undetermined parameters involved in the proposed model can be obtained through maximum Young’s module, deformation module, and limit deviator stress and linearity index of soils that can be measured from experiment directly or calculated by empirical formulas indirectly. The effectiveness of the proposed stress-strain model is examined by predicting stress-strain curves measured in plane-strain compression test on Toyota sand and undrained triaxial compression test on London clay. The fitting results of the proposed model are in good agreement with experimental data, which verify the effectiveness of the model.

An analytical method is proposed which predicts the non-linear stress-strain response of a CFRP laminate. The method uses a secant modulus iterative method and includes thermal effects due to the temperature difference of a laminate from its curing temperature. Details of the basic CFRP non-linear behaviour in transverse and in-plane shear loadings are given. Experimental data on 0°/±45°/0° balanced laminates are presented and compared with theoretical predictions.
