Abstract Composites composed of closed solid wall cells enclosing a fluid are examined in this paper. The analysis of their stiffness in compression includes the effects of fluids in the cell interiors. A specialized finite element program is developed to account for the internal pressure. Both two‐dimensional and three‐dimensional geometries are considered. The finite element calculations are then used to predict the compressive stiffness of fluid filled metal cell composites.
