Crushing behavior of honeycomb vs. foam under combined shear-compression loading

This paper conducts a combined compression-shear test on honeycombs and Kelvin foams to compare their yield envelopes. The honeycomb and foam specimens with a similar relative density are fabricated by using the additive manufacturing technique. The quasi-static and dynamic crushing behaviors under combined shear-compression are investigated by employing a universal testing machine and a rotatable Hopkinson bar system, respectively. Five loading...
