Abstract
In this paper the method of damage measurement of metal structure at the creep is proposed. In contrast to other methods, it allows the measurement of this damage to be carried out in the process of creep test without unloading and cooling of specimens. 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 repture is monotonically decreasing function of the applied stress. This conclusion is an experimental verification of the theoretical result, obtained earlier.
