FRACTURE ASSESSMENTS WITH ELASTIC FOLLOW-UP FOR COMBINED PRIMARY AND SECONDARY LOADINGS PART 2: NUMERICAL VALIDATION

Research output: Contribution to journalArticle

Abstract

This paper presents comparisons of finite element (FE) results with the J
estimation equations proposed in Part 1 for treating fracture under combined primary
and secondary loadings. The FE analyses are performed for a pipe with a
circumferential internal surface crack subjected to axial tension combined with
thermal loading. The crack depth and length, the relative magnitude of axial tension
and thermal loadings, loading sequence and material properties are systematically
varied. Based on the FE results, the applicability of the proposed equations in Part 1 is
discussed and new estimation equations obtained by modifying the existing equations
are proposed and validated.
