Abstract:Negative stiffness honeycombs are energy absorbers that absorb energy by transitioning from one buckling mode to another and their snap-through behavior in cells. They have a fundamental property as an energy absorber; in this type of absorber, negative stiffness causes reversibility after impact. In this study, the effect of negative stiffness honeycomb material in increasing energy absorption is investigated experimentally and numerically. The quasi-static tests are performed on negative stiffness honeycombs… Show more
