摘要：
We show a correlation between the loading characteristic of crack resistance (critical stress intensity factor) and the mechanical characteristics during dynamic indentation. We propose a procedure for monitoring a material in the stage preceding its fracture. We have obtained experimental results for isotropic pyrolytic graphite that support the feasibility of the procedure and the possibility of using it for nondestructive testing of graphitized carbon materials.
