DOI: 10.1016/j.ijsolstr.2019.08.011
Abstract: Abstract We present an analytical modeling framework and its analysis for thin piezoelectric metamaterial plates to enable and predict low-frequency bandgap formation in finite structural configurations with specified boundary conditions. Using Hamilton’s extended principle and… read more here.

DOI: 10.3390/nano12030541
Abstract: In this paper, the focus is on the free vibrations of locally resonant metamaterial plates with viscously damped resonators. Upon formulating a dynamic-stiffness model where the resonators are represented via pertinent reaction forces depending on… read more here.
