Abstract The mechanical properties and the operating life of a formed component are highly dependent on residual stress state. There is always high magnitude stresses in components by incremental sheet forming (ISF) due to localized deformation mechanism. Hence, thorough understanding generation ISF necessary. This study investigates mechanism for two process variants ISF, i.e., Single Point In...

In this study, single point incremental forming (SPIF) of Al-Li alloy sheets under different angles are studied via both experimental methods and numerical simulations. The effect angle on the geometric accuracy SPIFed component is studied. simulation results show that higher angle, lower stress at corner, leading to better geometrical accuracy, which also experimentally validated. It found hig...
