A SD-effect-incorporated nonlinear model for investigating the tension-compression asymmetry in stress–strain curves of fibrous composites was developed in Part I as a new application of the one-parameter plasticity model. In Part II of this investigation, the model is further developed to three-dimensional finite element models and is implemented in the finite element code ABAQUS; in addition, the model is validated against experimental results of stress–strain curves for unidirectional and angle-ply laminates under off-axis tension and compression. Last, parametric studies for a composite cantilever beam with and without SD effect are discussed to illustrate the features of the implemented model that is proposed herein.
