Generally, a solid material has the linear stress-strain response within a certain stress level, beyond which up to the failure the stress-strain relation becomes non-linear.
This paper presents a method of predicting the non-linear stress-strain response up to the tensile failure for an orthotropic lamina and a laminated composite consisting of orthotropic lamina. The present technique is restricted to the prediction of the stress-strain curve for plane anisotropic laminates with midplane symmetry subjected to uniaxial membrane load. The comparison between the analytical predictions and the experimental results shows that the predicted non-linear stress-strain responses approximately coincide with the experimental results.
