    Abstract: The problem of determining explicit formulas for a hollow cylinder under uniform internal pressure   is the thrust   of this study. The cylinder under consideration is made of the Blatz-Ko material †. In obtaining the required results, the radial displacement of the cylinder is sought by means of (an approximate) series solution   of an emerging boundary-value problem.
