超音速偏航流作用下功能梯度材料板的振动与屈曲
Vibration and Buckling of Functionally Graded Plates in Supersonic Yaw Flow
摘要
Abstract
Based on composite sheet theory and first-order piston aerodynamic theory with yaw angles, the aero-dynamic elastic model are established for functionally graded material plates in thermal environ-ments.Galerkin method is used to solve the critical buckling temperature and natural frequency of the model.The numerical examples are used to analyze the influence of the Mach number,the flow angle, the material composition index,the edge-thickness ratio,and the boundary conditions on the buckling critical temperature and the natural frequency of the functionally graded material plate.The results show that buckling critical temperature and natural frequency increase with the increase of the Mach numbers, but decrease with the increase of the ambient temperature.Moreover,the buckling critical temperature changes greatly when the deflection angle of airflow changes within a certain range.关键词
