Abstract
This paper presents the stress strength safety of LPG steel cylinder for various corner radiuses of upper round end plate and lower round end plate by using a finite element method. The FEM analyzed results indicate that the most influential elements is a corner radius of upper round end plate and lower round end plate rather than a thickness of LPG cylinder. But, the thickness of a steel cylinder is an important design element considering for a weight reduction of a cylinder. Thus, this paper recommends that the LPG steel cylinder thickness is 2.3~2.6mm and the corner radius of upper round end plate and lower round end plate is over 157mm as an optimum design for the maximum testing pressure of 3.04MPa.
