摘要：

A method is suggested for analytical determination of the optimum structure for highly porous material according to the criterion of minimum deformation stress. It is shown that calculation by the minimum stress criterion makes is possible to obtain in the optimum structural state a lower damping stress with greater work for deformation. Calculations are in good agreement with experimental results.
