Abstract

The stress strain state of homogeneous pipe subjected to internal pressure at elasto plastic loading and plane strain condition is analyzed. The plane strain condition appears in buried pipelines. By using FEA it is proved that the accuracy of presented methodic for determination of stresses and strains is quite acceptable. Dependences of stress strain state components distribution on value of inner pressure and Poison's ratio are also presented.
