Proceedings ArticleDOI
An initial investigation of the large strain and fatigue loading behavior of piezoelectric wafer active sensors
James Doane,Victor Giurgiutiu +1 more
TL;DR: In this article, the behavior of piezoelectric wafer active sensors (PWAS) under large strain and fatigue conditions was studied and the authors developed theoretical data to determine how the frequencies and resonance qualities change due to increased tensile loading.

Piezoelectric multilayer-stacked hybrid actuation/transduction system
TL;DR: In this paper, a novel full piezoelectric multilayer stacked hybrid actuation/transduction system consisting of at least two layers which include electromechanically active components is presented.
Journal ArticleDOI
Application of the Nondimensional Dynamic Influence Function Method for Free Vibration Analysis of Arbitrarily Shaped Membranes
TL;DR: In this article, a new formulation for the NDIF method (the nondimensional dynamic influence function method) is introduced to efficiently extract eigenvalues and mode shapes of arbitrarily shaped, homogeneous membranes with the fixed boundary.

Added Mass Estimation of Square Sections Coupled with a Liquid Using Finite Element Method
Kyeong Hoon Jeong,Myung Jo Jhung +1 more
TL;DR: In this article, the authors used the finite element method to extract the added mass effect on translational and rotation motions of square sections and applied it to the spent fuel storage design of a pressurized light water modulated nuclear power plant.
Journal ArticleDOI
Effects of distributed structural dynamic modification with reduced degrees of freedom
TL;DR: In this paper, structural modification has been applied to a plate clamped on all four edges in which a rectangular hole is cut out in the center as modification, and the frequency response functions (FRFs) of the original unmodified plate were obtained experimentally as well as numerically.
