Abstract : A nonlinear, plane-stress, laminate analysis program, NOLIN, has been developed which accounts for laminae nonlinearity under inplane shear and transverse extensional stress. The program determines the nonlinear stress-strain behavior of symmetric laminates subjected to any combination of inplane shear and bi-axial extensional loadings. The program has the ability to treat different stress-strain behavior in tension and compression, and predicts laminate failure using any or all of maximum stress, maximum strain, and quadratic interaction failure criteria. This document provides a brief description of the program including discussion of the flow of information and details of the input required. Sample problems and a complete listing of the program is also provided.
