Effects of hygrothermal conditions on free vibration behaviour of laminated composite structures

Abstract

Free vibration behaviour of laminated composite structure under combined hygrothermal load is investigated in this article. The responses are obtained numerically through a finite element model using hygrothermal dependent composite material properties. The convergence behaviour of the present numerical model has been established and validated by comparing the responses with those available open literatures. The effects of various hygrothermal conditions and geometrical parameters (curvature ratio, side-to-thickness ratio and aspect ratio) are examined in details.
