The application of fracture mechanics to the estimation of the failure reliability of products made of polymers and compounds, as well as an evaluation method for quality control and material development, requires geometry-independent parameters which react extraordinarily sensitively to structural changes in the materials. An essential prerequisite for a theoretically well-based material optimization is a knowledge about the connections of strength- and toughness-determined deformation and fracture mechanisms to structural quantities.
