Local compression fatigue property of roll core sandwich panel

When the honeycomb core sandwich panel (hereafter, HSP for brevity) is used as a floor panel, a dent is formed on the surface of it. If the depth of dent was deeper, it is changed into a new one. In order to change it efficiently, it is necessary to study a period for use as the floor panel applied...
