Damage localization in composite lattice truss core sandwich structures based on vibration characteristics
TL;DR: In this paper, a baseline-free NDE method was proposed to determine the debonding of truss bar in composite lattice truss core sandwich structures based on the uniform load surface curvature, and developed according to the synergy of gapped smoothing method and Teager energy operator.
Journal ArticleDOI
Damage detection of cracked beams based on wavelet transform
TL;DR: In this paper, a damage detection method based on a continuous wavelet transform is proposed and applied to analyze flexural wave in a cracked beam in order to identify the damage location and its extent.
Journal ArticleDOI
Efficient asymmetric transmission of elastic waves in thin plates with lossless metasurfaces
TL;DR: In this article, a generic framework for undistorted asymmetric elastic-wave transmission in a thin plate just using a layer of lossless metasurface was proposed and experimentally demonstrated.
Journal ArticleDOI
Creating micro- and nanostructures on tubular and spherical surfaces
TL;DR: In this paper, the authors developed a new technique to create micro and nanometer scale structures on curved free-standing objects by combining embossing/imprinting lithography approaches with mechanical loadings on elastic films.
Journal ArticleDOI
Determination of Young's modulus of individual electrospun nanofibers by microcantilever vibration method
TL;DR: In this article, a technique for measuring Young's modulus of a single electrospun polyacrylonitrile nanofiber using the vibrations of two microcantilevers coupled with the nanof fiber is presented.
