摘要: In this paper, a formulation for the buckling of cylindrical thin shells made functionally graded material (FGM) composed ceramic and metal subjected to external pressure varying as power function time is presented. The properties are in thickness direction according volume fraction power-law distribution. modified Donnell type dynamic stability compatibility equations obtained using Love’s shell theory. Applying Galerkin’s method then applying Ritz variational these different initial conditions taking large values loading parameters into consideration, analytic solutions critical parameter values. results show that affected by configurations constituent materials, variations expression variations. Comparing with those literature validates present analysis.
