Conclusions

  1. 1.

    Consideration of stability loss significantly lowers the mechanical adequacy of the model under consideration for simulating an actual FP with an OPS for deformations that are of practical interest.

  2. 2.

    The available SM for an FP with an OPS opens the possibility of controlling the PMC of FP by varying different parameters of the model: the GSE elongation factor in the direction of foaming; the coefficient of variation of the rod lengths; this makes it possible to regulate the FP structure and the PMC of the polymer-base: and, the reduced-length factor μ.

  3. 3.

    The software program that we developed for calculating the PMC of FP can be used hereinafter to perform numeric experiments in developing FP with a prescribed set of PMC in lieu of physical characteristics; this will significantly reduce time and labor outlays, and make it possible to investigate the deformation mechanism.
