Mixed mode fatigue growth of curved cracks emanating from fastener holes in aircraft lap joints
The ®nite element alternating method is extended further for analyzing multiple arbitrarily curved cracks in an isotropic plate under plane stress loading. The required analytical solution for an arbitrarily curved crack in an in®nite isotropic plate is obtained by solving the integral equations formulated by Cheung and Chen (1987a, b). With the proposed method several example problems are solv...
متن کاملThe Effect of Transducer Placement on the Monitoring of Fatigue Cracks Emanating from Fastener Holes
In situ ultrasonic methods for structural health monitoring have the potential to provide early detection of fatigue cracks in aircraft components, specifically cracks initiating from fastener holes. A dual angle beam technique based upon an incident shear wave and a spiral creeping wave propagating around the hole has been shown to be a viable configuration for monitoring of fastener hole crac...
متن کاملAnalytical Solution for Embedded Elliptical Cracks, and Finite Element Alternating Method for Elliptical Surface Cracks, Subjected to Arbitrary Loadings
Abstract-The complete solution for an embedded elliptical crack in an infinite solid and subjected to arbitrary tractions on the crack surface is rederived from Vijayakumar and Atluri’s general solution procedure. The general procedure for evaluating the necessary elliptic integrals in the generalized solution for elliptical crack is also derived in this paper. The generalized solution is emplo...
متن کاملDetection of cracks at rivet holes in thin plates using Lamb-wave scanning
This paper describes a Lamb-wave scanning method for the detection of notches simulating cracks at rivet holes in thin plates. The approach requires the generation of an ultrasonic So-Mode Lamb wave using an incident transmitter excited with a tone burst centered at a near non-dispersive frequency. Area scans are performed on a plate with a hole with a notch to generate times series information...
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...
