Abstract
We describe a method for the evaluation of the dynamic stress intensity factors under the action of dynamic loading. The method is based on the solution of the problem of limiting equilibrium for a cylindrical specimen of finite dimensions containing a circumferential crack. In the process of solution, we use the experimental load-time diagram. We establish a simple formula for the evaluation of the dynamic stress intensity factors depending on the history of loading of the specimen. The obtained results serve as a basis of an experimental procedure of determination of the crack-growth resistance of materials. The results of specially performed experimental investigations confirm the efficiency of the proposed formulas.
