Abstract:
The purpose of this thesis parametric study the natural frequencies and the criti-cal buckling multilayer composites truncated cone with the effect of lateral shear deformation. For this purpose five-bending tensile deformation equation of motion of the truncated cone shell in a suitable coordinate system have been studied. Then solve the five-coordinate movement for power series-are consid-ered. The natural frequencies and critical buckling force for the various truncat-ed cones with four different boundary conditions are calculated and the results with the results of similar conical shells with the same boundary conditions, tak-ing into account the effect of lateral shear deformation and also excluding the effect of deformation Compared. In this thesis, the effects of head angle, thick-ness, length of productive cone on natural frequencies and critical buckling force for two types of isotropic and cross-Play with the effect of lateral shear deformation is studied
