Based on the results obtained within the scope of the model of piecewise-homogeneous medium and three-dimensional stability theory, the accuracy of the continuum theory is examined for laminated incompressible materials undergoing large deformations. Estimation of the accuracy of the continuum theory is illustrated by numerical results for the particular models of composites when the layers are hyperelastic materials with the elastic potential of the neo-Hookean type (Treloar's potential). Based on this the influence of the layers' thickness and their stiffness on the accuracy of the continuum theory is determined. (C) 2001 Elsevier Science Ltd. All rights reserved.
