dc.description.abstractThe fundamental natural frequencies of curvilinear fiber composite doubly curved panels are optimized. Doubly curved panels are used in numerous components of the structural frames of aerospace vehicles. The variable stiffness performanceis achieved by changing the fiber path to the curvilinear fiber path function in the composite structures. The structural model is developed based on the virtual work rule. The target is to attain the best fiber paths with maximum fundamental frequencies. An eight-layer composite doubly curved panel with two forms of boundary conditions is considered as anexample in this research. The boundary conditions include; CCCC, FCFC. Von-Karman kinematic strain relations are utilized and the FSDT is used to generalize the equation for the doubly curved panel. Generalized Differential Quadrature (GDQ) theory of solution is applied to solve the differential governing equations of motion. Numerical results reveal the efficiency of the curvilinear fiber path concept on the frequencies of the doubly curved panel. The optimum fiber path function of each layer is offered for the free vibration study.
