Dynamic Resonance of Curved Panels in Adverse Hygrothermal Environment

Abstract EN

The present paper deals with the dynamic resonance of composite curved panels subjected to periodic dynamic loadings.

The effects of various parameters of four-sided clamped composite curved panels at elevated temperatures and moisture concentrations on the principal instability regions are investigated by finite element method which is used to study the antisymmetric angle-ply square plates.

The results show that instability of composite plates occurs for different parameters in adverse hygrothermal environment.

The experimental and numerical investigation is also carried out for four-sided clamped boundary condition for vibration and buckling of curved panels in hygrothermal environment.
