Analysis of forming capacity of HCT490X and DX57D depending on strain rate
Original language description
To evaluate forming capacity in sheet metal forming, experimentally determined Forming Limit Curves (FLC) are often used. These curves represent the forming limits of a material. The most widely used approach to experimentally determine the onset of necking of sheet metals is formulated in EN ISO 12004-2. The first goal of this work is to investigate limit strains for dual-phase steel HCT490X (commonly referred to as DP500) with a nominal thickness of 0.6 mm and deep drawing steel DX57D with a nominal thickness of 0.7 mm. The second goal is to evaluate the influence of punch speed (resulting in strain rate) on the position of forming limit curve for materials HCT490X and DX57D. The FLC curve is measured with Nakajima test on a universal testing machine BUP 600. The test set-up and the shape of samples follow EN ISO 12004-2. The stochastic, isotropic and high contrast pattern was applied on samples and was measured using 3D photogrammetric system ARAMIS by GOM. The punch movement velocity was gradually changed, and experimentally measured results are compared with numerical simulation in AutoForm Forming R8.
