The influence of ovality of the shell-type construction to stress-deformed state

Abstract

Abstract There are many standards that tell us in which ranges the geometry of equipment, piping systems or individual elements of the facility can change. The authors of the article set the task to assess the change in the state of one equipment with possible permissible geometric deviations. As part of the study of the experimental sample, a combination of different variants of ovality was modeled at different pressures up to the yield point. It is shown that there are situations that can reach the yield point at significantly lower loads on the apparatus, as a result of the occurrence of zones of local stress concentrations. Recommendations are given on the real maximum stress-deformed state in the investigated apparatus depending on geometric deviations.
