This paper studies the shearing process that exists when automotive shredder residue (ASR) is reduced from up to fist sized chunks into pellets through the use of a granulator. The process is simulated with a punch and die. The experiments provide an understanding of the effects of clearance between knives, tool geometry, speed of shearing (strain rate), and plastic material being sheared. The results of the experiments improves the understanding of the shearing process and deformation mechanism. The results were compared to punching and blanking of metals. The conclusions can be used to formulate knofe design and operating conditions for granulators.
