Finite Element Analysis of a Plate using ANSYS Workbench

This project presents a Finite Element Analysis (FEA) of a plate, conducted using ANSYS Workbench. The analysis includes detailed investigations into the plate's behavior under various loading conditions and constraints. The project encompasses structural analysis, modal analysis, and buckling analysis. The structural analysis explores the plate's response to axial loading and bending, presenting deformation patterns and stress distributions. The modal analysis examines the plate's natural frequencies and mode shapes, providing insights into its dynamic characteristics. Finally, the buckling analysis determines the critical loads at which the plate may experience instability. The document includes screenshots of the model, meshing, boundary conditions, and results, offering a comprehensive understanding of the FEA process. This assignment is provided by a student on Desklib, a platform that offers AI-driven study tools and resources for students.

1. Solid Model Using ANSYS Workbench
As directed in the Youtube Reference video, a sketch was created in DesignModeler. Later the
dimensions were modified as mentioned in the Assignment. Below is the screenshot of the same.
Figure 1: Thin Plate sketch in DesignModeler
The variable dimensions for this case were:
Plate width =1000mm; Plate Height = 160mm; Hole Position = 200mm ; Hole Rafius =70mm; Notch Radii
=15.5 mm and Notch Offset =4.5mm.

2. Meshing
The part is meshed with Hex-Dominant Element. The total Element count is 12188 elements and
56193 nodes.
