In order to study the dynamic response characteristics of circular extended foundation wind turbine in mountainous areas, a 1:10 scaled model test was carried out on 2MW turbine, and deformation under random load were analyzed by ABAQUS numerical calculation. The results show that: (1) has different stress types windward side leeward side. components are subjected tensile stress, while compress...

In the present research, a unified formulation for free vibration analysis of the bidirectional functionally graded conical and cylindrical shells and annular plates on elastic foundations is developed. To cover more individual cases and optimally tailored material properties, the material properties are assumed to vary in both the meridian/radial and transverse directions. The shell/plate is a...

An analysis has been presented of the effect of elastic foundation and uniform in-plane peripheral loading on the natural frequencies and mode shapes of circular plates of varying thickness exhibiting bi-directional functionally graded characteristics, on the basis of first order shear deformation theory. The material properties of the plate are varying following a power-law in both the radial ...
