Mixed-Mode Stress Intensity Factors for Surface Cracks in Functionally Graded Materials Using Enriched Finite Elements
Three-dimensional enriched finite elements are used to compute mixed-mode stress intensity factors (SIFs) for three-dimensional cracks in elastic functionally graded materials (FGMs) that are subject to general mixed-mode loading. The method, which advantageously does not require special mesh configuration/modifications and post-processing of finite element results, is an enhancement of previou...
متن کاملPhotoelastic Determination of Mixed Mode Stress Intensity Factors
A two dimensional finite model with inclined crack at different crack angles are being analyzed in mixed mode condition using photo elasticity method for the determination of Stress Intensity Factors. The well-known Sih’s equation and three points deterministic approach is used for the determination of stress intensity factors. The effects of biaxial load factor, crack angle, size factors were ...
متن کاملErrors Estimation for Evaluating Mixed-Mode Stress Intensity Factors for Cracks Emanating from Sharp Notches Using Simulated Photoelasticity
In this paper, errors involved in extracting stress intensity factors from photoelastic fringe pattern, which were simulated for crack estimated. The estimated errors do not contain the errors associated with the optical apparatus, but only consist of the errors associated with discretization and extraction of data for SIF’s calculation to accomplish that. A series of fringe pattern were simula...
متن کاملEstimation of the Stress Intensity Factors for Surface Cracks in Spherical Electrode Particles Subject to Phase Separation
Experiments have frequently shown that phase separation in lithium-ion battery electrodes could lead to the formation of mechanical defects, hence causing capacity fading. The purpose of the present work has been to examine stress intensity factors for pre-existing surface cracks in spherical electrode particles during electrochemical deintercalation cycling using both analytical and numerical ...
متن کاملStress intensity factor of mode-III cracks in thin sheets.
The stress field at the tip of a crack of a thin plate of elastic material that is broken due to a mode III shear tearing has a universal form with a nonuniversal amplitude, known as the stress intensity factor, which depends on the crack length and the boundary conditions. We present in this paper exact analytic results for this stress intensity factor, thus enriching the small number of exact...
