چکیده مقاله
This paper aims at presenting a new efficient element for free vibration of Axially Functionally Graded Materials FGMs non prismatic beams using Finite Element Method FEM Using concept of Basic Displacement Functions BDFs , two node element extends to three node element for obtaining much more exact results using FEM First, BDFs are introduced and computed using energy method such as unit dummy load method Afterward, new shape functions are developed in terms of BDFs during the procedure based on the mechanical behavior of the element in which presented shape functions benefit generality and accuracy from stiffness and force method, respectively Finally, deriving structural matrices of the beam with respect to new shape functions; free vibration of the FGM beam is studied using finite element method for all types of AFGM beams and the convergence of FEM has been studied The results from free vibration is in perfect agreement with those of previously published
