1. The system of creep equations (1), or respectively (11), fairly well reflecting the mechanical basis of the process and embracing all stages of creep, does not create additional mathematical difficulties, when solving concrete problems. 2. The use of equations of the type (1) allows us to match the problem concerned with the determination of the stress—strain state, with the problem concerned with the time elapsed up to the failure. 3. The accumulation of damage in the material leads to an intensive re-distribution of stresses in the disc. Unloading of a region close to the state of failure takes place, while regions of lesser damage are being loaded. Consideration of this process allows us more accurately to estimate the time up to the failure of the construction, in comparison with methods of solution of creep problems according to the scheme of a “steady stress state.”
