Strength differential effect in age hardened aluminum alloys [PDF]

International Journal of Plasticity, 2017
Abstract The strength differential (SD) effect, as reported in literature over the past decades, is a discrepancy between the axial stresses in compression and tension. This study investigates the SD effect in aluminum alloys using both experiments and numerical simulations.
