摘要: For characterizing the geometry independence of fracture mechanics parameters, geometrical factors are used, which make possible an estimation requirements on specimen without any further experiments. polymers, experimentally determined vary in a wide range, as compared to metals. The relationships between and were found be generally valid for independent rate loading (quasi-static, impact) crack propagation behaviour (stable, unstable).
