Development and Numerical Justification of the Specimen for the Surface Crack Growth Rate Tests

In this work, based on the numerical analysis of the stress-strain state, the specimen for the surface crack growth rate tests at normal and elevated temperatures is developed. The known test methods for the surface crack growth rate determining are analyzed and the requirements for the specimen are...
