| Description |
The calculation model for determining of residual durability of plate with straight corrosion-mechanical crack under long-term static tension and multiple time concentrated quasi-dynamic load is proposed. The model based on the energy approach for a study of delayed crack growth, models of pulsed load applying and the main mechanisms of corrosion-mechanical crack propagation. Based on this model, the dependence of residual life of the plate of X60 pipeline steel on a number of time concentrated quasi-dynamic loadings is investigated. |
