Journal ArticleDOI
Interaction of elastic waves with a Griffith crack
TL;DR: In this article, the problem of diffraction of normally indicent longitudinal and antiplane shear waves on a Griffith crack located in an infinite, isotropic elastic medium is considered.
Journal ArticleDOI
Inversion of leaky Lamb wave data by simplex algorithm
TL;DR: In this article, a numerical procedure is presented for the inversion of leaky Lamb wave (LLW) data to determine certain material properties of a waveguide, using a modified version of the simplex algorithm.
Journal ArticleDOI
Scattering of Lamb waves from a rivet hole with edge cracks
Zensheu Chang,Ajit Mal +1 more
TL;DR: In this paper, a hybrid method called the global local finite element method was used to analyze the Lamb wave propagation in an infinite plate containing a circular hole, with or without edge cracks, both theoretically and experimentally.
Journal ArticleDOI
Elastic waves in a fiber-reinforced composite
S.K. Bose,Ajit Mal +1 more
TL;DR: In this article, the authors studied the propagation of time-harmonic elastic waves in a fiber-reinforced composite, where the circular fibers were assumed to be parallel to each other and randomly distributed with a statistically uniform distribution.
Journal ArticleDOI
Longitudinal shear waves in a fiber-reinforced composite
S. K. Bose,Ajit Mal +1 more
TL;DR: In this paper, the propagation of time harmonic longitudinal shear waves in a composite with randomly distributed parallel fibers is studied and the phase velocity and the damping of the average waves are obtained as functions of the statistical and the mechanical parameters of the system.
