Abstract Scope Tensile testing of metals with ultrasonic vibration has shown a consistent reduction in flow stress, known as acoustic softening. However, the use of ultrasonic vibrations in complex deformation processes is less efficient in transmitting acoustic energy leading to lower softening. This experimental study compares the softening behavior of AA2024-O under tensile loading and incremental sheet forming (ISF) of a groove-shaped geometry. By varying the feed rate and sheet thickness, the total imparted acoustic energy and, therefore, the acoustic energy density can also be varied. The results show that the magnitude of acoustic softening is lower in incremental sheet forming compared to tensile tests. The relationship between acoustic energy density and material softening is correlated. Microhardness measurements were conducted to compare the degree of strain hardening. Electron backscatter diffraction (EBSD) was performed to compare grain size and texture evolution.
