Free Vibration Analysis of Curved Panels

Mishra, Sandeep (2014) Free Vibration Analysis of Curved Panels. BTech thesis.



In the present work, vibration behaviours of cylindrical and/or conical curved laminated /isotropic panel structures have been investigated. The models of cylindrical and conical shell panel have been developed based on first order shear deformation theory (FSDT) using the ANSYS parametric design language (APDL) code in ANSYS 13 environment. The model has been then discretised using a 8 noded isoparametric element (SHELL 281) from ANSYS 13 element library. The model has also been validated by with comparing the its vibration responses with the results of a known literature and the convergence behavior of the present simulation model has also been obtained. Finally, substantial effect of various parameters on the frequency of vibration such as fibre orientation in various layers and number of layers in case of the composite cylindrical shell panel and element size and mode number in case of isotropic/laminated, conical/cylindrical shell panel has been investigated
