    A new bimodular material model has been developed for the determination of reference-surface positions. The model is applicable to linear elastic isotropic and orthotropic composite rectangular thin plates of different aspect ratios. The basic concept of the model is to convert the actual material section to an equivalent one. The upper part of the cross section above the reference surface is assumed to be in compression, while the part below is assumed to be in tension. The reference-surface positions are determined independently of the plate boundary conditions and the loading. In the examples discussed here, the results of the reference-surface positions using the present model are found to be very close to neutral-surface positions determined by other methods, such as closed form and finite element methods. Moreover, the new material model does not require any iterations unlike the other models. Hence, it can be incorporated easily into linear and geometrically nonlinear structural analysis computer programs.
