We propose a method for determining dynamic stress intensity factors for hollow cylindrical specimens with circular crack of finite length under impact tension. The solution of this problem is reduced to the numerical solution of an eigenvalue problem with the use of experimental loading–time diagrams. Simple formulas are obtained for determining dynamic stress intensity factors, depending on the history of loading of a specimen. The comparison of the values of dynamic stress intensity factors calculated by the formulas indicated and by the finite-element method testifies to the reliability of the results obtained.
