Abstract
In this work, the damping, vibration, and instability characteristics of the rotating sandwich plate with a 3D-printed honeycomb core and glass/carbon fiber-reinforced composite skins are analyzed. The laminated composites are created using the vacuum-assisted hand layup method, and honeycomb cores are fabricated using a 3D printer. An experimental investigation was done to examine the vibrations of 3D-printed honeycomb sandwich composites. A finite element method-based higher-order shear deformation theory (HSDT) is used to obtain the governing equations for the sandwich plate. Further, a thorough parametric study is conducted to examine the effect of rotational speed, aspect ratio, core thickness, hub radius and setting angle on the vibration, damping, and instability characteristics of the glass/carbon fiber composite sandwich plate with a 3D-printed honeycomb core. From the obtained results, it can be concluded that the skin layer's hybrid fiber reinforcement greatly influences the vibration, damping, and instability characteristics of the rotating 3D-printed honeycomb sandwich plates.
期刊介绍:
Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses.
Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering.
The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
