This paper presents finite element solutions for elastic-plastic J for circumferentially cracked pipes under combined mechanical and thermal loads in terms of the V/Vo factor used within a strain-based failure assessment diagram. In this study, 3-dimensional finite element analyses are conducted to calculate the V-factor under combined mechanical and thermal load. It is found that estimation of V/Vo is sensitive to the method used for its evaluation. For larger thermal stresses, currently proposed estimation methods are overly conservative.

Three Dimensional Finite Element

Two and three-dimensional finite element analyses of a butterfly valve assembly subjected to static fluid pressure were carried out using commercial code ANSYS. Good agreement between the experimental and finite element results were obtained. Sensitivity of results to various boundary and loading conditions was also investigated.
