Abstract
In present study, vibration and harmonic behaviors of annular sector sandwich plate of two orthotropic composite materials are analyzed using FEM technique. Sandwich plate made of two face sheet and one core sheet in middle has been modelled using an ANSYS APDL FEM tool. A suitable finite element model is developed and proposed based on first order shear deformation theory. The model has been discretized using appropriate elements i.e. 8-node solid 185 for core sheet and SOLSH190 for face sheet from the ANSYS element library. Effect of varying face sheet thickness is demonstrated on vibration as well as harmonic behaviors of sandwich plate and related findings are discussed briefly. Effect of sector angle has also been demonstrated. The authenticity of the proposed methodology has been verified by comparing the simulation results with available literature. It can be observed that the results obtained are in good propinquity and presently proposed model shows the results with adequate accuracy.
