| Abstract: | By introducing a dimensionless parameter to couple the two objectives,weight and radar absorbing performance,into a single objective function,a multi-objective optimization procedure for the radar absorbing sandwich structure (RASS) with a cellular core is proposed.The optimization models considered are one-side clamped sandwich panels with four kinds of cores subject to uniformly distributed loads.The average specular reflectivity calculated with the transfer matrix method and the periodic moment method is... |
