Elastic Wave Scattering from Griffith Cracks
نویسندگان
چکیده
To model elastic wave scattering from fatigue cracks in metals, studies were conducted of wave scattering from artificial cracks using ultrasonic spectroscopy. The cracks are of two dimensional planar strips oriented at various angles and embedded in diffusion bonded titanium alloy. The crack is assumed to behave as a Griffith crack and expressions (derived by Achenbach1) to describe diffracted field of elastic waves are used to analyze experimental results.

Moving Three Collinear Griffith Cracks at Orthotropic Interface
This work deals with the interaction of P-waves between a moving central crack and a pair of outer cracks situated at the interface of an orthotropic layer and an elastic half-space. Initially, we considered a two-dimensional elastic wave equation in orthotropic medium. The Fourier transform has been applied to convert the basic problem to solve the set of four integral equations. These set of ...
متن کاملUltrasonic Scattering by Planar and Non-planar Cracks
Problems of elastic wave scattering by surface-breaking and near-surface cracks are of considerable current interest for ultrasonic nondestructive evaluation. Ultrasonic scattering by planar cracks near or at the free surface of a semi-infinite elastic homogeneous medium has been studied theoretically by many authors. References to recent papers on this subejct can be found in [1], [2] and [3]....
متن کاملElastic wave propagation and scattering in solids with uniaxially aligned cracks.
In this article, elastic wave propagation and scattering in a solid medium permeated by uniaxially aligned penny-shaped microcracks are studied. The crack alignment refers to the case in which the unit normals of all cracks are randomly oriented within a plane of isotropy. The analysis is restricted to the limit of the noninteraction approximation among individual cracks. Explicit expressions f...
متن کاملApplication of MOOT to Scattering of Elastic Waves from Compound Inclusions
We show how MOOT (method of optimal truncation, a convergent T-matrix scheme) can be used to calculate elastic wave scattering from compound inclusions; i.e. inclusions which themselves contain flawsinclusions, voids, or cracks. The general equations are derived, and they are solved for a particular axially-symmetric case a cracked spherical jnclusion immersed in fluid. The crack edge is a circ...
متن کاملAnalysis of Ultrasonic Elastic Waves in Vibrothermography Using Fem
Vibrothermography is a promising technique that uses elastic ultrasonic wave excitation in solids for quality maintenance, e.g. in aerospace and automotive industry to monitor the integrity of surface or subsurface features. Vibrothermography allows for defect selective imaging using thermal waves that are generated by elastic sound or ultrasound waves. The mechanism involved is local friction ...
