Abstract:Abstract: The solid-air composites has been proposed to make a new movement of the composite material design. The estimating method of the internal hydrostatic pressure distribution has already been formulated by applying numerical analysis considering the interfacial load transmission. The purpose of the present study is to apply an experimental planning method to the internal hydrostatic distributions calculated by inputting the structural design factors as design variables to the FE model, and to investigate the simplification of the optimum design of the solid-air composites. In this optimization, it was supposed that the static load dispersion of the solid-air composites was able to be evaluated by using the internal hydrostatic pressure distribution. Consequently, the reasonable optimum solution by controlling the distribution of the hydrostatic pressure was obtained under the conditions of the static indentation and the simple support.
