摘要: The effect of the core cell shape on shock absorption characteristics biomimetically inspired honeycomb structures has been numerically investigated. finite element models test specimen composed five cells identical mass have constructed, and numerical simulations run PAMCRASH. dimensions sides as well angle between shown to influence structure. with regular hexagonal is found show best absorbing capacity, rectangle-like are provide good characteristics.
