In-plane crushing response of tetra-chiral honeycombs ...

2019-8-1 · This is caused by the fact that the two reasons which help to increase the crushing strength as under the quasi-static loading no longer exist: the crushing distance is the same for honeycombs with different α values since the deformation occurs row by row under dynamic loading; meanwhile, there is no "bulge effect" and the honeycomb shows the "I" mode deformation pattern. As a result, the dynamic crushing strength …
