Journal ArticleDOI
Composite 3D-printed metastructures for low-frequency and broadband vibration absorption
TL;DR: This work presents a class of materials (labeled elastic metastructures) that supports the formation of wide and low-frequency band gaps, while simultaneously reducing their global mass.
Journal ArticleDOI
Review of Second Harmonic Generation Measurement Techniques for Material State Determination in Metals
TL;DR: In this article, the authors present a comprehensive review of the current state of knowledge of second harmonic generation (SHG) measurements, a subset of nonlinear ultrasonic non-destructive evaluation techniques.
Journal ArticleDOI
Designing perturbative metamaterials from discrete models.
Kathryn H. Matlack,Marc Serra-Garcia,Antonio Palermo,Sebastian D. Huber,Chiara Daraio,Chiara Daraio +5 more
TL;DR: A perturbative method is proposed for the systematic design of mechanical meetamaterials, where each element of the discrete model is associated with individual geometric features of the metamaterial, through the weak interaction between the unit cells.
Journal ArticleDOI
Experimental characterization of efficient second harmonic generation of Lamb wave modes in a nonlinear elastic isotropic plate
TL;DR: In this paper, the authors characterized the efficiency of Lamb wave mode pairs to generate the cumulative second harmonic in an undamaged aluminum plate and experimentally confirmed the theoretically predicted ratios of the rate of accumulation of the second harmonic amplitude versus propagation distance.
Journal ArticleDOI
Evaluation of radiation damage using nonlinear ultrasound
Kathryn H. Matlack,James J. Wall,James J. Wall,Jin-Yeon Kim,Jianmin Qu,Laurence J. Jacobs,H. W. Viehrig +6 more
TL;DR: In this article, nonlinear ultrasound was used to monitor radiation damage in two reactor pressure vessel (RPV) steels, and the results showed a clear increase in the measured acoustic nonlinearity from the unirradiated state to the medium dose, and then a decrease from medium dose to high dose.
