Vibration analysis of stiffened plates with initial geometric imperfections
https://orcid.org/0000-0001-8225-2225
This paper presents the vibration analysis of stiffened plates with initial imperfections, using both conventional and super finite element methods. Von Karman theory was utilized so as to formulate the plate element. Eccentricity of the stiffeners is also taken into account and they are not limited to be placed on nodal lines. Consequently, any configuration of plate and stiffeners can be modelled. Nonlinear finite element equations are solved using arc-length method and backbone curve is extracted accordingly. The accuracy of proposed methodology is established in comparison with previous results. Finally, the effect of geometric imperfection on vibration characteristics of stiffened plates is studied extensively.
