A blade is cantilevered from a rigid rotating cylinder. Determine the fundamental frequency of vibration of the
blade, f, when the cylinder is spinning at a rate of Ω . Figure 54.1 Rotating Cantilever Blade Material Properties

The problem is solved in two different ways:
• Using Elastic Shell Elements (SHELL63) • Using 3-D Solid Shell Elements (SOLSH190) Spin (centrifugal) softening is used. Since the cylinder is rigid, the base of the blade has its displacements constrained. A static prestress analysis is performed to include...
