Analysis reveals that hydrogen affects durability and energy criteria improve creep failure predictions.
The durability of a thin-walled plane specimen made of 22K steel under the influence of hydrogen and creep was determined using the finite element method (FEM). A comparative analysis of the results obtained using the classical equations of creep theory and the energy approach were compared. The satisfactory convergence of the results with experimental data is established. However, the energy criterion allows for a more accurate prediction of the time to failure compared to the classical equation.
