Plastic behaviour of clamped double-layer foam-filled double-arrow negative Poisson’s ratio core sandwich beams
This paper proposes a double-layer foam-filled double-arrow negative Poisson’s ratio core sandwich (FDNPS) beam that combines the high static load-bearing capacity of corrugated panels with the energy-absorption capabilities of metal foam. In this paper, the yield criterion for the double-layer FDNPS beam’s cross-sec...
