Abstract:This paper studies the uncertainty in the mechanical response of foam-filled honeycomb cores by means of a computational multi-scale approach. A finite element framework is adopted to determine the response of a periodic arrangement of aluminum honeycomb core filled with PVC foam. By considering uncertainty in the geometric properties of the microstructure, a significant computational cost is added to the solution of a large set of microscopic equilibrium problems. In order to tackle this high cost, we combine… Show more
