“Effect of Underlay Dimension to Cutting characteristics of Polystyrene Bars Subjected to Wedge Indentation”

抄録

This research was aiming to compare shearing characteristics of Polystyrene (PS) square bars that subjected to indentation of a symmetry (42°) blade and mounted on Al5051 plate underlay with bars that subjected to indentation of a symmetry (42°) and mounted on Al5051 anvil. In order to compare load resistant from cutting process, stroke of breakage and deformation of Polystyrene bar, the cutting velocity was varied ranging from 5 to 65 mm/min. The result revealed that the maximum load resistant for cutting in case of use Al5051 anvil is lower than use Al counter plate and both was found that increase related to cutting velocity. While, both process have the same indentation displacement for bars breakage. Moreover, the deformation of PS bars when using anvil in cutting process depend on cutting velocity remarkably.
