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