 note = {P(論文), Sheared surfaces of Polyvinylchloride (PVC) are not smooth as expected, although the strength is lower than that of conventional metals. The shearing mechanism for PVC has been studied by using a machining set up in a scanning electron microscope (SEM). A visio-plasticity method is used to investigate strain distribution of the work. The direct SEM observation results show that shearing phenomenon of PVC is different from that of conventional metals, because of shape of the crack in the shearing process. The punch side crack initiates on the severely domed surface. The fracture mode of the initiating crack is mode I (opening crack tip) and that of the propagating crack is mode II (shearing on plane). The strain distribution calculated by the method shows that the punch side crack initiates along the maximum principal strain rate direction and propagates along the maximum shear strain rate direction. On the other hand, the die side crack also initiates along the maximum principal strain rate direction and may propagates along the maximum shear strain rate direction.},
