A method is given for determining cracking resistance based on the strain diagram for stable crack growth; the specimen is loaded to give a set rate of crack extension or with given speed for the clamps. The critical value of the Jintegral has been determined by calculating the work of strain for a hypothetical specimen composed of a nonlinearly elastic material whose cracking resistance is equal to that of the actual one. Two forms of implementation are considered: simplified and numerical. The results are compared with those from standard methods and show that the proposed method is promising as it can be based on tests on a single specimen with a simple technique. |
