Abstract:Sandwich panels with pyramidal cores made of thin-walled tubes absorb energy very well, but their main limitation is the complexity of producing such a structure. This study utilized a novel self-interlocking assembly technique to fabricate the lattice core, significantly reducing fabrication time and material requirements. Experimental tests and finite element analyses were performed to investigate the effect of geometrical parameters on the out-of-plane characteristics of sandwich panels with pyramidal thin-… Show more
