Nowadays in the world, due to increasing development of fabrication and design, fabrication of composite materials with variable stiffness are provided. These composites are widely used in various industries, especially in the aviation industry due to the simultaneous benefits of metal and composite. As an innovation in this research, the frequency analysis of variable stiffness fiber-metal laminated plates under thermal load are investigated using the semi-analytical finite strip method based on the classical laminated plate theory. In this regard, the effects of boundary conditions, stacking sequences, number of layers and effect of geometric dimensions on the frequency behavior of mentioned plates are studied. The results show that frequency of variable stiffness fiber metal laminated plates by increasing the temperature, thickness and boundary constraints in different boundary conditions are increased. Also, the stacking sequences and plate dimensions are affected the frequency of plates. To check the validity, some of results are compared with several different references and show a good agreement.
