The transfer matrix method is an analytical method for investigating the vibrations in many
structures such as beams, sheets, and shells. In this method, the inverse of “zero matrices” …

In the present article, a higher order shear deformation theory is used to develop a finite
element model for the free vibration analysis of a rotating functionally graded material plate …

Bladed disks found in turbomachines are complex structures whose vibration characteristics
are generally determined by exploiting the symmetry properties of their nominal …

Vibration characteristics of cracked rotating tapered beam are investigated by the p-version
finite element method. In the present formulation, the shape functions enriched with the …

A GAS turbine is a component of a rotary power engine that drives combustion gases at high
temperature and pressure. This is mainly used as a power source for power plants and …

This survey is concerned with the problem of determining the dynamic modal characteristics
(natural frequencies and associated mode shapes) of rotating beams. Modal characteristics …

Introducing the concept of basic displacement functions (BDFs), a new beam element is
presented for the analysis of rotating tapered beams. BDFs are obtained using the energy …
