A differential quadrature analysis of vibration for rectangular stiffened plates
H. Zeng,Charles W. Bert +1 more
TL;DR: In this article, a differential quadrature analysis of free vibration of plates with eccentric stiffeners is presented, where the plate and the stiffeners are treated separately and simultaneously governing differential equations are derived from the plate dynamic equilibrium, the stiffener dynamic equilibrium and equilibrium and compatibility conditions along the interface of a plate segment and a stiffener.
