Abstract

The structure elements multistaged model of damage is suggested. It is connected with the creep curve and dependence oj logarithmic decrement on time. The numeral evaluation of damage on stainless steel samples with suggested model is made.

Keywords:

damage, creep curve, logarithmic decrement of oscillations, cantilever samples
