Optimization of sandwich plates with truss cores

Sandwich plates with truss core have many advantages with respect to other structures, including the plates with the honeycomb cores. Besides the architectural possibilities, which are the consequence of their favorable appearance, these structures can carry equal or even higher loads than other similar structures. In this paper is presented an attempt to optimize the mass of the sandwich plate's structure, which is subjected to simultaneous action of loads due to the transversal shear force and the bending moment. In comparison to the corresponding sandwich plate with the honeycomb cores, the plate with the truss core is almost equally efficient form the aspect of the mass decrease.
