Dynamic analysis of FG stepped truncated conical shells surrounded by Pasternak elastic foundations

Đang chuẩn bị nút TẢI XUỐNG, xin hãy chờ

This research presents a continuous element model for solving vibration problems of FG stepped truncated conical shells having various material properties and surrounded by Pasternak foundations. Based on the First Order Shear Deformation Theory (FSDT) and the equations of the FGM conical shells, the dynamic stiffness matrix is obtained for each segment of the shell having constant thickness. |
