Abstract

Measuring techniques and evaluation procedures for determining impact energies of polymeric specimens in instrumented impact tests are discussed. In particular, high sensitivity striker tups capable of measuring small loads with high accuracy are introduced and the importance of sufficiently fast electronic measuring systems for obtaining true load traces are illustrated. But even when determined with appropriate test techniques the measured impact energy might not in all cases represent the true fracture energy for breaking of the specimen. Kinematographic recordings of the movement of the broken specimen halves after the impact process show that a considerable portion of the measured impact energy is transferred into kinetic energy of the moving specimen halves. The difference of the conventionally measured impact energy and the kinetic energy of the moving specimen halves is introduced as the true impact fracture energy.
