Abstract: In this paper the method of damage measurement of metal structure atthe creep is proposed. In contrast to other methods, it allows to carry out the measurement of this damage in the process of creep test without unloading and cooling of specifens. Experimental damage curves during creep are obtained as a result of test data processing by the suggested method. The analysis of these curves leads to a conclusion that the material damage at rupture is monotonically decreasing function of applied stress. This co...
