“…The nonlinear strains are underestimated by the model for angle-ply laminates suggesting that interlaminar damage and fiber scissoring effects, as considered in, e.g. Kuznetsov and Partsevskii, 24 should be incorporated in the laminate deformation model to improve the accuracy of prediction.…”

“…Such a behavior is common for angle-ply laminates of traditional continuous fiber composites; it is caused by several mechanisms including development of interlaminar damage and fiber rotation. [24][25][26] Such nonlinearity mechanisms are not taken into account in the present model, which leads to progressive deviation of the predicted stressstrain curve from the experimental one with increasing strain.…”

In an attempt to fully utilize the mechanical properties of bast fibers in polymer-matrix composites, unidirectional (UD) or quasi-UD flax-fiber-reinforced composites are being developed and characterized. Their response in tension is markedly nonlinear both in on-and off-axis loading. A semiempirical tensor-linear model is applied to describe such deformation nonlinearity in active combined loading. The deformation model of UD ply, combined with an elementary laminate theory, is used to predict the stress-strain curves of laminated composites in tension. Reasonable accuracy of prediction is demonstrated for fiber-dominated layups.
