This chapter is concerned with the vibration analysis of linear plates
employing the mixed formulation based three-node flat triangular shell elements in
Chapter 2. Square, circular and skew plates are studied. In particular, circular plates
with various aspect ratios and boundary conditions are included. As a special example
to reveal the features of the membrane component of the shell elements a plane stress
problem is presented.
Keywords: Vibration analysis, plates, square, circular, skew.
