概要
In this paper, an internal burst pressure equation applicable to all types of planar and non-planar flaw in wallnocad Aniden ta rotinnollu aloccifu ninnari nan nlonor flow in wn11 thinnad ning In this paper, an internal burst pressure equation applicable to all types of planar and non-planar flaw in wall thinn ed straight pipes was proposed. An idea to rationally classify planar/non-planar flaw in wall thinned pipes was proposed, based on the experimental observa tion focused on the fracture mode. The results point out the importance to distinguish axially and circumferentially long flaws in wall thinned pipes. 1.緒言
