SPRING BACK ANALYSIS OF PERFORATED STEEL SHEET METAL USING FINITE ELEMENT METHOD
International Journal of Research in Science and Technology
unpublished
Sheets are deformed to required shapes by plastic bending with the help of punch and die set in sheet metal working. However, after withdrawing the applied load, the contour assumes a different shape than that of die because of release of elastic stress in the metal. This elastic strain recovery is commonly called as springback. Springback effect is a major cause of concern for metal forming industries which leads to inaccuracies in final product produced and eventually leads to problems in
