Abstract

A method for processing the results of tests on samples of crack growth rate to determine the stable part of the kinetic diagram of obtaining the average values ??of fracture toughness properties in tests of several samples. Performed fractographic study of fracture surfaces of compact samples after the tests on the crack growth rate in order to confirm the accuracy of determining the upper limit of sustainable development of the crack area proposed method of processing the test results.
