Journal ArticleDOI
Fabrication and electromagnetic characteristics of electromagnetic wave absorbing sandwich structures
TL;DR: In this paper, the radar absorbing structures (RAS) having sandwich structures in the X-band (8.2-12.4 GHz) frequencies were designed and fabricated, and the reflection loss characteristics for multi-layer sandwich structures were calculated using the theory of transmission and reflection in a multi-layered medium.
Journal ArticleDOI
Estimation of dynamic structural displacements using fiber Bragg grating strain sensors
TL;DR: In this article, structural displacements are estimated using strain signals from fiber Bragg grating (FBG) sensors without displacement measurement. But the results show good agreement with those measured directly from laser displacement sensors.
Journal ArticleDOI
Optimal placement of piezoelectric sensors and actuators for vibration control of a composite plate using genetic algorithms
Jae-Hung Han,In Lee +1 more
TL;DR: In this article, the placement of piezoelectric sensors and actuators in a smart composite place has been studied with consideration of controllability, observability and spillover prevention.
Journal ArticleDOI
Postbuckling and vibration characteristics of piezolaminated composite plate subject to thermo-piezoelectric loads
Il-Kwon Oh,Jae-Hung Han,In Lee +2 more
TL;DR: In this article, postbuckling and vibration analysis considering large thermopiezoelastic deflections are performed for fully symmetric and partially eccentric piezolaminated composite plates.
Journal ArticleDOI
Displacement field estimation for a two-dimensional structure using fiber Bragg grating sensors
TL;DR: In this paper, the displacement field estimation of a dynamically excited plate using a transformation matrix based on a modal approach was discussed, in order to reduce systematic displacement estimation errors due to aliasing.
