| Abstract: | This paper made a comprehensive analysis of the confusion frequently occurring in the nomenclature and denotation for various kinds of stresses in calculating the strength of embeded pipes,and the mixing up of and errors in the definition of a combined stress and an admissible stress in calculating as well.In terms of mechanic practice,the paper gave a relevent explana- tion of how to correctly express axial,tengential,radial and principal stresses and how to deter- mine a combined stress and an admissible stress.And finally,based on the principle of mechan- ics,the paper presented proper steps for calculating the strength of embeded pipes. |
