The task of assessing the durability of the elements of the boom section of the clamp-forming machine, made from a 45´45´5 mm angle is considered. This object is modeled by a plate with a crack. Analytical relations are given and the stress intensity coefficients and their rate of change near potentially possible crack-like defects are investigated. The criterion crack lengths are determined based on the results of experimental studies.
