Paper acquires a certain profile when it is cut. This profile can be described as having a wear side and a burr side. The purpose of this work is to search for differences in the response of paper and PET subjected to a collision regarding which side is being collided. To investigate this difference, paper and PET specimens were slid through a 45 degree slope that was set to collide against a plastic counter plate. An acoustic emission (A.E.) sensor attached to the counter plate registered the vibration produced by the collision of the profile of the specimen. As a result, it was found that it is possible to find differences between the A.E. response of the wear side and burr side collision.
