6.1 A rectangular sandwich hull plate comprises a part of the flat bottom of a ship. Consider this as a rectangular plate under a uniform lateral distributed loading. Po from the water pressure, and clamped along all edges. The steel sandwich faces are 0.125" thick, and the foam-core depth h = 2.5". The panel is 4 ft. wide and 6 ft. long, and the ship draws 14 ft. of water, where seawater weighs 64 lb/ft?. The steel face properties are: E = 30 ~ 10%psi, v=0.3, au ==20,000 psi. What is maximum stress in the sandwich panel? What is the maximum deflection? Use Table 6.4.
