Journal ArticleDOI
Analysis of a femoral hip prosthesis designed to reduce stress shielding
TL;DR: The hypothesis that through redesign, a total hip prosthesis can be developed to substantially reduce stress shielding is explored and the results show that the new design produces a more physiological stress state in the proximal femur.
Journal ArticleDOI
Interaction of the primary anti-symmetric Lamb mode (Ao) with symmetric delaminations: numerical and experimental studies
TL;DR: In this paper, the interaction of an ultrasonic guided Lamb wave mode with delamination type defects in a quasi-isotropic laminated composite plate has been studied, using both simulations and experiments.
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
An energy-based model for ballistic impact analysis of ceramic-composite armors:
TL;DR: In this article, an analytical model for the ballistic impact behavior of ceramic-composite armors is presented, based on wave theory and energy balance between the kinetic energy of the projectile and the wave energy.
Journal ArticleDOI
Modelling of attenuation of Lamb waves using Rayleigh damping: Numerical and experimental studies
TL;DR: In this paper, the authors derived the Lamb mode attenuation constants in terms of the attenuation coefficient, group velocity and central frequency of excitation of Lamb mode, using the Rayleigh damping model.
