Free Vibration Analysis of Composite Structure under Thermal Condition


Article Preview

A nonlinear thermal vibration characteristic of the laminate composite thin shell structures under linear temperature field is investigated by finite element method (FEM). The natural frequencies of the composite laminated thin shell structures with different boundary conditions and stacking sequence are calculated and analyzed. Numerical results show that the natural frequencies of the structure are affected by the temperature, boundary conditions and the stacking sequence; the proper stacking angle can change the natural frequencies; the effect degree on the natural frequencies of symmetric composite structures is different from that of the antisymmetric one. These conclusions can provide some guidance to structure design and heat-resistant design of composite structures.
