Vibration analysis of laminated composite circular plates with radial slots
MetadataShow full item record
Vibration characteristics of laminated composite annular circular plates with radial slots are studied by Finite Element Method (FEM). As theoretical background, vibration analysis of orthotropic annular circular plates, mechanics of laminated composites and finite element modeling are summarized. Laminated composite annular circular plates with radial slots are introduced. The APDL program in ANSYS is developed for the titled problem and verified by the available literature for the annular circular plate. Then, the effects of lamination parameters on natural frequencies are investigated.
