Incremental Sheet Forming Analysed by Tensile Tests

To study material behaviour under conditions encountered in ISF operations tensile tests have been carried out on material taken from the walls of pyramidal products. The shape of the stress-strain curves depend on orientation. Tests in the direction of punch movement show an overshoot indicating a change in strain path, tests across that direction do not. From this it is concluded that the major direction of deformation in the walls is perpendicular to the direction of punch movement. There is no indication of a severe deformation in the direction of punch movement, either stretch or shear. The level of hardening in the material is less than expected from the macroscopic changes in dimensions. Apparently the forming operation in ISF causes additional softening of the material
