A new formulation for estimating maximum stress intensity factor atthe mid plane of a SENB specimen: Study based on 3D FEA
Journal Title: Frattura ed Integrità Strutturale - Year 2014, Vol 8, Issue 29
Abstract
In this investigation, three-dimensional elastic finite element analyses have been conducted tocompute the stress intensity factor (KI) in a SENB specimen with varied thickness (B) and crack-length to widthratio (a/W). The results indicate that the magnitude of KI depends on B, and significantly varies along the crackfrontfrom surface to the center of the specimen. The maximum value of KI is found at mid plane of thespecimen. Based on the present 3D finite element calculations an effort is made to propose the new analyticalrelationship between maximum KI and specimen a/W, which helps to estimate maximum KI by only knowingspecimen geometry and applied load.
