Influence of mechanical properties of the sheet material on formability in single point incremental forming

Model identification and FE simulations: Effect of different yield loci and hardening laws in sheet forming

“…The results from Henrard et al (2005), He et al (2005a) and He et al (2005b), confirmed by other research teams (Fratini et al, 2004;Iseki, 2001), show that concerning the exact shape prediction at the end of the process, the type of constitutive models is not a key factor. The discrepancy between the prediction from a 40° pie mesh and the experiment is shown in Fig.…”

Incremental Metal Forming Processes in Manufacturing

“…In all the cases, they formed the components using hemispherical ended tool (not a freely rotating ball tool) till failure and generated the forming limit curves for incremental forming. Later, Fratini et al (2004) have carried out experimental study to understand the effect of material properties on the formability in SPIF for commonly used sheet materials, namely, copper, brass, high-strength steel, deep drawing quality steel, AA1050-O, and AA6114-T4, in sheet metal industry. They measured strain-hardening constant (K), strainhardening exponent (n), normal anisotropy index (R), ultimate tensile strength, and percentage elongation (%PE) of all the materials by conducting tensile tests.…”

Ductile Fracture Prediction in Rotational Incremental Forming for Magnesium Alloy Sheets Using Combined Kinematic/Isotropic Hardening Model

“…Thus, several studies have investigated the influence of the main material parameters and process variables on formability, and improve the formability in ISF. [15][16][17] Kim and Yang [18] proposed a double-forming technique to improve formability, assuming that only shear deformation occurs in the material. Plus, Park et al [19] studied and showed the possibility of cup incremental forming of a magnesium sheet at RT with a rotational tool, where the tool rotates itself.…”
