Elastic twisting metamaterial for perfect longitudinal-torsional wave mode conversion被引量:2
《Applied Mathematics and Mechanics(English Edition)》2023年第4期515-524,共10页Shengjie YAO Yijun CHAI Xiongwei YANG Yueming LI 
Project supported by the National Natural Science Foundation of China(Nos.U2033208,52192633);the Natural Science Basic Research Plan in Shaanxi Province of China(No.2021JQ-006);the China Postdoctoral Science Foundation(No.2020TQ0241);the Innovative Scientific Program of China Nuclear Power Engineering Co.,Ltd。
In this work,we design a twisting metamaterial for longitudinal-torsional(L-T)mode conversion in pipes through exploring the theory of perfect transmodal FabryPerot interference(TFPI).Assuming that the axial and radia...
