In high performance lightweight structures, the insertion of relatively more dense dampers of any type may increase the total mass substantially and alter the mass distribution significantly. The objective herein was to determine the optimum location, number and orientation of DSLJ inserts within a typical sandwich panel, and thereby to assess the efficacy of two different optimisation approaches to this problem; a parametric optimisation and the Adaptive Indicator-Based Evolutionary Algorithm (IBEA). Both approaches were used to maximise the damping while minimising the additional mass of the damping inserts applied to the structure. Although the parametric approach was faster and easier to implement, the Adaptive IBEA identified significantly better configurations in many cases, especially where veering occurred, in one case improving modal loss factors more than fourfold vs the parametric method. Solutions were identified with large increases in modal loss factors but only small increases in mass vs the empty structure.

Mathematical modeling and experimental study of damping behavior of a cantilever carbon fiber–reinforced polymer composite hollow member with metal inserts

“…Boucher et al (2013) performed analytical, FE, and topological optimization studies to find the optimum locations of the inserts made of high damping material in the voids of the honeycomb cells (without increase in density). This study was extended further by Aumjaud et al (2015) for finding the optimum parameters of double-shear lap joint (DSLJ) inserts in a honeycomb sandwich panel using parametric optimization as well as adaptive indicator-based approaches. In these approaches, the damping was maximized while minimizing the extra masses of the inserts mounted on the structure.…”

Micro Fracture Behavior of Composite Honeycomb Sandwich Structure

“…Rigid sandwich structures are widely used in military fields such as aerospace, shipping, and armored vehicles because of their high specific strength, specific rigidity, specific energy absorption, and other characteristics. With the continuous advancement of sandwich structure research, there has been much work carried out on the optimal design of the sandwich structure in order to meet the acoustics, thermal, and mechanical property requirements for different fields [ 1 , 2 , 3 , 4 ]. Namvar et al [ 5 ] used improved multi-objective particle swarm optimization with a genetic algorithm (MOPSOGA) to study the optimal design of a medium-thickness hexagonal honeycomb sandwich plate—highly accurate optimal velocity, inertia weight, and acceleration coefficient parameters were obtained.…”

A sustainable approach of damping treatment for aluminium honeycomb sandwich structures

“…Boucher et al [20] concluded that a partial occupation of the voids could be more efficient in terms of added weight. A parametric optimisation and the adaptive indicator-based evolutionary algorithm was employed by Aumjaud et al [22] in selecting damping insertion locations, focussing on the first two mode shapes.…”
