Abstract

The project for the dome tester stand is a continuation from a group of four that worked on the stand in Spring of 2020. The project itself is based around the Erichsen Cupping test to test the material properties, in our application specifically, observing the forming limits of strain in deep drawing applications of sheet metal. Testing pieces in varying lengths from 4” x 4” squares to 4” x 0.5” strips to the depth that necking begins on the piece to determine the limit before cracks appear using a hemispherical punch to draw the material sample clamped between two dies. The main goal of this project was to understand what all is necessary to test these materials properly and to create a process that will be able to provide future students with the hands-on opportunity to test materials and formulate forming limit diagrams for various materials on their own at The University of Akron.
