Stress Intensity Factors for Complex-Cracked Pipes Based on Elastic Finite Element Analyses
Volume 6A: Materials and Fabrication, 2015A complex crack is one of severe crack that can occur at the dissimilar metal weld of nuclear piping. A relevant fracture mechanics assessment for a pipe with a complex crack has become interested in structural integrity of nuclear piping. A stress intensity factor is not only an important parameter in the linear elastic fracture mechanics to predict ...

This paper presents a new numerical method for obtaining the complex stress intensity factor with an interface crack in bi-materials using photoelastic isochromatic fringe numbers N. The theoretical solution of stress field at the crack tip was deduced from Muskhelishvilis stress function and an undetermined term σ0 which is a function of material ...

Damage tolerance analysis (DTA) of complex aircraft structures requires stress intensity correction factor (β-factor) solutions that cannot be accurately or practically determined with handbook solutions. Typically, these β-factors can be related to the load transfer to adjacent structures and to irregular geometries.

Abstract This paper addresses the problem of determination of the Stress Intensity Factor (SIF) for a crack in a bimaterial interface from the displacement fields obtained through Digital Image Correlation (DIC). Center cracked and edge cracked bimaterial specimens, as well as asymmetric 4-point bend specimens are tested and displacements are ...

This work presents the results from an analysis which considers the interaction between a crack and surrounding microcracks. The method of complex variables is used to derive explicit expressions for the stress intensity factors. The results are computed and discussed for a variety of geometrical configurations of microcracks, with the intent of ...

The simple method developed by Kachanov (1985) for multiple interacting cracks in homogenous medium is extended to predict complex stress intensity factor for multiple split type interface cracks. Calculations are implemented for two equal cracks and infinite row of periodic cracks at the interface between two dissimilar isotropic materials.

Description is given of a complex variable-variational method to investigate the stress intensity factor associated with the mode II cracking. In this work, a cracked plate is decomposed into two subregions with edge cracks. According to the theory of anisotropic elasticity the stress and displacement series which satisfy all basic equations and stress-
