The paper presents a preliminary design study on the structural response of a boxy composite sandwich truck tank subjected to hydraulic head loading. Structural sandwich panels can be considered as a special type of composite laminate where two thin, stiff, strong and relatively dense face sheets are separated by a thick, lightweight and compliant core material. Such sandwich structures have gained widespread acceptance as an excellent way to obtain extremely lightweight components and structures with every high bending stiffness, high strength and high buckling resistance. Among the applications where sandwich materials and structures are being used successfully, spacecraft and aircraft structures, ship hulls and ship superstructures, high speed trains, wind turbine blades and cargo containers can be mentioned. The study is approximate in that it considers a 2-D cross section of the composite sandwich truck tank. It is performed using a high-order sandwich theory formulation in which the elastic responses of the face laminates are accounted for individually, and in which the transverse flexibility of the sandwich core is included. Thus the model allows the sandwich panel thickness of the truck tank to change during deformation, and the model accounts for the existence of transverse normal stresses. It includes a presentation, as well as a description and is concluded with a numerical study, showing the characteristic features of the elastic response of a composite sandwich truck tank section subjected to hydraulic head loading.
