Vibrational Analysis of Partially Perforated Rectangular Plates with Circular Perforations 2021-28-0199

Starting from aerospace to agriculture, partially perforated plates are being used in almost all major spheres of technology. Though a substantial amount of work has been done in this area, the effect of the diameter of circular perforations on the vibrational characteristics of rectangular sheets made of SS 416L has not been reported. The present work aims to bridge this gap through the modal analysis of the said system using respective computational software. In addition to the diameter of circular perforations, the effect of the thickness of the partially perforated rectangular sheets on the free vibrations of the system is also investigated. Through circular and parallel orientations of perforations, this work aims at establishing an understanding of the changes in vibrations depending on the pattern of perforations. The inferences reported through the variation of such parameters are expected to lay foundations for further research in this field, thereby bridging some critical gaps in the current literature.
