Notes:
This paper describes for breaking behaviors on the surface layer of a white-coated paperboardduring indentation of a center bevel blade. Cutting load response of the paperboard was measuredregarding the indentation depth of the blade and the deformation flow in a side view of the paperboard wasobserved by a CCD camera in order to investigate the effect of blade tip angle on the surface failures of thepaperboard. The surface breaking strength of paperboard was analyzed by using Finite Element Method(FEM). Through the experiment and FEM simulation, the followings were revealed. 1) There is a certaincritical value of tip angle C at which an inflection load response disappears and also the surface failuresare restricted. 2) When the tip angle is less than the C, there is an inflection point as the surface-layerbreaking and its surface breaking point was strongly related to the maximum principal stress on thesurface. 3) After the surface breaking, the deformation flow and its cutting resistance are strongly affectedby the de-laminated and the raised-up of the inner-layer
