Abstract (EN): A miniaturized testing device of the end load split (ELS) test was conceived to evaluate fracture energy release rate under pure mode II loading of young bovine cortical bone tissue. Since crack length is not possible to monitor during propagation, classical methods cannot be applied to determine fracture energy in this material. Hence, an equivalent crack technique, which does not necessitate the crack length surveillance, was used to assess the equivalent crack extent. The applied data reduction scheme is based on the specimen compliance, beam theory and crack equivalent concept, providing the assessment of the energy release rate. The method was dully validated through a numerical analysis, by means cohesive zone modeling.
