Experimental and Simulation Stress Strain Comparison of Hot Single Point Incremental Forming
Induction assisted single point incremental forming
(IASPIF) is a flexible method and can be simply utilized to
form a high strength alloys. Due to the interaction between the
mechanical and thermal properties during IASPIF an evaluation for
the process is necessary to be performed analytically. Therefore, a
numerical simulation was carried out in this paper. The numerical
analysis was operated at both room and elevated temperatures
then compared with experimental results. Fully coupled dynamic
temperature displacement explicit analysis was used to simulated the
hot single point incremental forming. The numerical analysis was
indicating that during hot single point incremental forming were a
combination between complicated compression, tension and shear
stresses. As a result, the equivalent plastic strain was increased
excessively by rising both the formed part depth and the heating
temperature during forming. Whereas, the forming forces were
decreased from 5 kN at room temperature to 0.95 kN at elevated
temperature. The simulation shows that the maximum true strain was
occurred in the stretching zone which was the same as in experiment.
