Optimum Design of a Sandwich Plate with a Hole or Notch

Abstract

Nowadays, due to the development of the sandwich core series and the progression of the higher degree of accuracy required for each thickness of sandwich plate, optimum design of the structural sandwich plate has been needed. We have found several papers on the optimum design of laminated plates. They deal with optimum density or optimum fiber direction of each ply, and optimum orthotropic layers under uniaxial and biaxial compression. But we have not been able to find any paper on the optimum design of a sandwich plate with a hole or notch which produces sandwich plate with a hole or notch, which searches least weight or cost per bending strength.
