Özet:

 

The dynamic stability of a non-homogeneous elastic conical shell under a time dependent uniform external pressure varying as a power function  is investigated in this study.  Dynamic stability and displacement  compatibility equations of the non-homogeneous elastic conical shell  under external pressure are obtained.  Applying Galerkin's method,  fundamental equations are reduced to a time dependent differential  equation with variable coefficients. Then, by applying the method of  Sachenkov and Baktieva (1978), general formulas for dynamic and static  critical loads, wave numbers, and the corresponding critical time,  critical impulse and dynamic factor are obtained.  From these  formulas, formulas for a homogeneous isotropic elastic shell are found.  The effects of non-homogeneity and the power of time in the  external pressure expression on the critical parameters are studied  through pertinent computations.  It is observed that these factors  have appreciable effects on the critical parameters of the problem in  the heading.
