Forced vibrations of functionally graded annular and circular plates by domain‐boundary element method

Abstract: Axi‐symmetric dynamic response of functionally graded circular and annular Mindlin plates with through‐the‐thickness variations of physical properties is investigated by a new domain‐boundary element formulation. Three governing partial differential equations of motion of the inhomogeneous plate are converted to integral equations by utilizing the static fundamental solutions of the displacement components. These integral equations are then spatially discretized by dividing the entire domain into a number of c… Show more

“…For the analysis of the free transverse vibration characteristics of the stepped circular plate, the eigenvalues and eigenvectors can be easily obtained by solving the standard matrix of equation (21). e physical modal shape can be readily yielded by substituting the corresponding eigenvectors into equations ( 15)- (17) for the given natural frequency.…”

“…en, Eshraghi and Dag [17] developed a new domain-boundary element formulation to investigate the axis-symmetric dynamic response of functionally graded circular and annular Mindlin plates with through-the-thickness variations of physical properties. Lam and Amrutharaj [18] employed a novel hybrid method to analyze the natural frequencies of a rectangular plate with stepped thickness variations and different edge boundary conditions, which had incorrect continuity conditions at stepped sections as was proposed by Dickinson [19].…”
