Free Vibrations of a Trapezoidal Plate with an Internal Line Hinge

This paper deals with a general variational formulation for the determination of natural frequencies and mode shapes of free vibrations of laminated thin plates of trapezoidal shape with an internal line hinge restrained against rotation. The analysis was carried out by using the kinematics correspo...

The analysis was carried out by using the kinematics corresponding to the classical laminated plate theory (CLPT).

The developed algorithm allows obtaining approximate analytical solutions for mentioned plate with different geometries, aspect ratio, position of the line hinge, and boundary conditions including translational and rotational elastically restrained edges. It allows studying the influence of the mentioned line on the vibration frequencies and respective mode shapes. The algorithm can easily be programmed and it is numerically stable. Additionally, as a particular case, the results of triangular plates can be easily generated.Fil: Quintana, Maria Virginia. Consejo Nacional de Investigaciones Científicas y Técnicas.
