This paper represents the authors´ contribution to Part A of the third World
Wide Failure Exercise where a constitutive model is proposed which considers
stiffness degradation and plastic strain accumulation for the prediction of
stress-strain curves and failure envelopes of 13 test cases, involving various
continuous fiber-reinforced laminates with polymeric matrix materials.
The model calibration by means of the provided material data is described and
the limits of applicability of the proposed constitutive model are discussed.
Finally, the predictions are presented as being obtained without any
experimental results available.
