Stress Intensity Factor (SIF) analysis on the Pressurized Base Weld Component (PBWC) Materials a Review

Abstract

This paper presented comprehensive review of literature of past years research work already done in proposed field is presented. The work includes the research work published in various journals and conferences, articles, magazine, available in open literature. The literature review focus on Stress Intensity Factor (SIF) analysis in both surface and depth direction and residual stresses concentration of the Pressurized Base Weld Component (PBWC). Stress intensity is used in fracture mechanics to predict the stress intensity near the crack tip which is caused by residual stresses. In present investigation effect of stress intensity factor over the pressurized weld component has been done on the basis of LEFM, residual stresses and previous studies so far to predict the effect on the crack growth in a pressurized base weld component in any NPP as we know the property of the welded zone of a pipe differs from its parent metal. For a design engineer it is very important to ensure the safety of the nuclear reactor as large amount of energy is transferred when the nuclear reaction takes place. A failure in the piping can be hazardous not only to the environment but also to the human lives and money. Review work very useful to us find the research gap in the proposed field.
