Thông tin tài liệu:

Geometrically nonlinear free vibration of microbeams partially supported by a threeparameter nonlinear elastic foundation is studied in this paper. Equations of motion based on the modified couple stress theory (MCST) and a refined third-order shear deformation beam theory are derived using Hamilton’s principle, and they are solved by a finite element formulation.
