The solid-air composites will be proposed to make a new movement of the composite material design. The purpose of the present study is to investigate the static load dispersion function caused by the internal hydrostatic pressures by applying numerical analysis. To simplify the evaluation of the static load dispersion, it was supposed the admissible stress field, where each stress field in closed cells is individual and two different stress fields being in both sides of a cell wall satisfy the equilibrium of forces through the cell wall. Non-linear deformation under in-plane indentation of the solid-air composites was incrementally simulated by using the finite element formulation based on displacement method. It was shown that the assumption of admissible stress field on the interfacial load transmission is useful in evaluating the static load dispersion because the numerical results were well in agreement with the experimental ones.
