Popis: When a local compression load is vertically applied on a face sheet of Honeycomb core sandwich panel (hereafter, HSP for brevity), a dent will be formed at relatively low force. Therefore, local compression tests of HSPs with different core height were carried out for a peripherally clamped specimen and a bottom face fixed specimen. From obtained results, the follows were summarized: 1) There was no effect of core height on strength. 2) Two peaks on load — displacement curve appeared for the peripherally clamped specimen. But, one peak appeared for a bottom face fixed specimen. 3) A peak load at first time for a peripherally clamped specimen was least for all. A peak load at second time for a peripherally clamped specimen was higher than that for a bottom face fixed specimen. 4) An Energy absorption for a peripherally clamped specimen was superior to that for a bottom face fixed specimen, because of a deflection observed for the only peripherally clamped specimen.
