... to longitudinal stretching of the beam. The core topology has a similar influence upon the initial peak load of clamped beams to that of the simply supported beams: sandwich structures with a corrugated core are 10–25% stronger than their counterparts with a Y-frame core. The initial peak load of sandwich beams...
