... to an electrical input. In this study, a specimen of a hyperplastic elliptic DE membrane is considered to observe the structural dynamics and aerodynamic characteristics under external flow of air subjected to electric excitation. For the structural dynamic characteristics, a finite element model of the membrane...

... Abstract The purpose of this paper is to introduce a new simple explicit single step time integration method with controllable high-frequency dissipation. As opposed to the methods generally used in structural dynamics, with a consistency experimentally chosen of second order, the new method...
