Study and analysis of the influence of stresses arising in a damaged thin-walled cylindrical container during compression

The subject of the article is important today; it is concerned with study of the effect of stresses, which occur in thin-walled cylindrical containers, such as tanks of fuel-servicing trucks, tankers, railroad tankers, and other containers operated under pressure, which are utilized in various sectors of the national economy. The goal of the undertaken researches is study and analysis of the effect of stresses, which occur in a thin-walled cylindrical container as a result of an inclined dent. Test results showed that during study of the effect of stresses, which occur in the damaged area of a thin-walled cylindrical container, it was discovered that their values depend on the angle of the dent's edge with respect to the container. Moreover, stresses in the damaged area decrease with an increase of the angle and maximum values occur when axes of a dent's edge and container are parallel with each other. Timely maintenance by applying metal bands to the damaged area greatly decrease stresses, especially if rhomboid bands are used.
