Abstract

To determine the value of springback coefficient of sheet metal the cylindrical bending tests were conducted. The experimental tests of bending process were carried out using special device which allows to measure the value of sheet springback. As a test material we used the AMS 5604 alloy sheet metal with a sheet thickness of 1 mm. The numerical simulations by finite element method of the cylindrical bending tests were conducted using LS-Dyna program. The simulations were conducted at the ambient temperature (20 °C) and at elevated temperatures: 400 °C, 500 °C, 600 °C, 650 °C and 700 °C. The results indicated that the value of springback coefficient of the sheet decreases with the increasing of temperature. Furthermore, during the bending process at analysed temperature the linear variation in sheet thickness is observed. The forming temperature value influences the value of limit strains of the sheet and determines the final shape of product.
