A new plate finite element model for rotating plate structures with constrained damping layer

Surface Treat Method to Improve the Adhesion between Stainless Steel and Resin: A Review

“…Different stress states of the same material in the same environment will lead to different deformations and crack states. In fracture mechanics, the fracture mode of cracks is usually divided into three models, 76 as illustrated in Figure 15 . 77 Among them, mode I cracks belong to the open mode cracks, and the member I is mainly subjected to tensile load perpendicular to the crack direction.…”

Constrained-layer Damping Applied to DCJ Vibration Isolation Design

“…Malgaca [11] forced the vibration of smart laminated composites to actively control the materials and performed ANSYS simulations of vibration suppression using different damping materials that yielded results similar to the experimental results. Xie et al [12] used CLD to suppress the vibration of rotating plates, indicating that thickening the CLD layer increased the deformation of its damping layer and accordingly improved its vibration reduction performance. Hong et al [13] adjusted the damping of fiberglass reinforced plastic (FRP) propeller blades through lamination angle; proposed a method for predicting structural damping; and demonstrated that adjusting structural damping can effectively reduce blade vibration.…”

Vibration prediction of rotating composite fan blades comprising viscoelastic damping treatments

“…However, a limited number of studies concerns the dynamic behaviour of rotating structures with constrained viscoelastic layers. Most of them are limited to rotating plates [3,4] or beams [5,6], which do not account for the complex geometry and structure of current composite turbine blades [7]. In addition, the mechanical properties of the damping layer are often considered as constant [3,4] even though the modulus of viscoelastic materials is known to be strongly frequency-dependent.…”

“…Most of them are limited to rotating plates [3,4] or beams [5,6], which do not account for the complex geometry and structure of current composite turbine blades [7]. In addition, the mechanical properties of the damping layer are often considered as constant [3,4] even though the modulus of viscoelastic materials is known to be strongly frequency-dependent. In the aforementioned literature, parametric studied are performed to investigate the influence of the properties and dimensions of the constrained viscoelastic layer, and of the rotation speed on the modal damping of the rotating structure.…”
