Journal ArticleDOI
Semiempirical Models of the Solar Atmosphere. II. The Quiet-Sun Low Chromosphere at Moderate Resolution
TL;DR: The SRPM 305 model presented in this article reproduces the observed intensities of CO lines at 4.466 μm, at both the disk center and near the limb, by using C and O abundances consistent with recent literature low values.
Journal ArticleDOI
Creep damage assessment in titanium alloy using a nonlinear ultrasonic technique
Sony Baby,B. Nagaraja Kowmudi,C.M. Omprakash,D.V.V. Satyanarayana,Krishnan Balasubramaniam,Vikas Kumar +5 more
TL;DR: In this article, a nonlinear domain (second harmonic amplitude) was used to evaluate the second harmonic amplitude (SHA) of a titanium alloy for in-service evaluation of creep damage.
Journal ArticleDOI
Structural health monitoring of composite structures using Lamb wave tomography
TL;DR: In this article, the authors used the newly identified energy of the earliest Lamb wave signals as the reconstruction parameter, modifying the sensor configuration from conventional geometries, and normalizing the Lamb wave energy data of the defective sample with respect to that of the defect-free sample.
Journal ArticleDOI
Interaction of guided Lamb waves with an asymmetrically located delamination in a laminated composite plate
TL;DR: In this article, the primary anti-symmetric Lamb mode (Ao) was studied through both numerical simulations and experiments employing the air coupled ultrasonic technique, and the presence of the "mode converted turning modes" was also validated through the experiments in this study.
Journal ArticleDOI
Inversion of composite material elastic constants from ultrasonic bulk wave phase velocity data using genetic algorithms
TL;DR: In this paper, the reconstruction of material stiffness properties of unidirectional fiber-reinforced composites from obliquely incident ultrasonic bulk wave data, employing an inverse technique based on genetic algorithms, is described.
