Empirical Formula and Method of Design for Elliptic Shell Vessel

概要

論文の詳細を見る
As to a special vessel, whose cross section is elliptic or approximately elliptic, the design formulas are not decided yet. In the previous paper the authors reported the experimental results together with the theoretical analysis on the strength of the vessel of this sort. The analysis, however, is attended with very complicated calculations so that it can not be used for practical design. Therefore, in this paper, the representation of the maximum stresses of the vessel as the functions of its principal dimensional elements is considered using the results of the previous experiments ; and moreover the validity of a practical design formula, which is based on the maximum stresses, is proved by authors' analytical theory for usual design range.
