Comparison Of Experimental And Simulation Results Using Erichsen Cupping Test Of Titanium Alloy Ot 4-1

Titanium alloy is known for its higher tensile strength and ability to hold high temperatures thereby deforming at larger loads. Hence, it is incorporated in major appliances in the aerospace industry and automotive sector. Erichsen Cupping test is a ductility test performed in the sheet metal forming process in major industries. OT 4-1 material is selected for experimentation and the simulation using PAM STAMPTM software. Both the experimentation and simulation tests are carried out at a temperature of 23 +/- 5 degrees C under controlled conditions. Blank holder, die and punch are the major components in the standard stamping and the punch is allowed to form an indentation on the blank with a minimal force and minimal stroke. The maximum stress obtained is 0.085847 Pa. The formability limit diagram, formability index and the stress graphs are determined in the current research from the simulation and compared with the experimental values. The future work would determine the aerospace and automotive applications by analytically developing new material models.(c) 2021 Elsevier Ltd. All rights reserved.
