摘要
The influence of long-term quasi-static loading on characteristics of deformation stress and fracture of vessels operating under pressure is examined. It is proposed to account for parameters of accumulated stress in order to estimate the state of material in these conditions. The physicochemical properties of material connected with different regimes of static, long-term, and cyclic quasi-static impacts which are used for estimating limit states of equipment working in conditions of long-term quasi-static loading are studied.
