Free vibration of isotropic plates with various cutout configurations using finite elements and design of experiments

Year: 2020

Type: conference-paper

Abstract: This work represents a finite element analysis of free vibration of isotropic plates with different cutout shapes, areas, locations and aspect ratios. Modal analysis was carried out using the ANSYS APDL software to evaluate the fundamental frequencies. ANSYS model was validated in the first stage and showed good agreement with the selected literature works. Furthermore, the selected cutout parameters were investigated to assess which parameter is more effective on the frequency. It is found that these parameters was overlapping, therefore Design of Experiments was conducted. Results revealed that the aspect ratio of the cutouts is the most significant factor on the fundamental frequency.
