Robust Stress-Classification of Pressure Components Using the GLOSS and GLOSS R-Node Methods

Abstract

The GLOSS and GLOSS r-node methods are used to classify stresses in pressure components. The classification scheme is akin to the prevailing ASME Boiler and Pressure Vessel Code procedures. The proposed method is applied to a cylinder flat-head configuration for thin as well as thick heads, and the stress classification methodology is outlined. The methods described in this paper can be readily applied to a general three-dimensional pressure component configuration.
