Influence of strain rate on the position of FLC curves for steel DC05

Popis výsledku v původním jazyce

Experimentally determined forming limit curves (FLC) are often used to evaluate the forming capacity when forming sheet metal. These curves represent the forming limits of the material. The most widely used procedure for the experimental determination of the failure limit of sheet metal is formulated in EN ISO 12004-2. The FLC curve is measured by the Nakajima test on a BUP 600, universal testing machine. The test arrangement and sample shape follow EN ISO 12004-2 except for the punch speed, which has been increased from 2 mm/s to 10, 14 and 17 mm/s respectively. The ARAMIS noncontact optical system by GOM was used for strain measuring. To ensure the quality of the measurements, a stochastic mesh was applied to the samples, and an Erichsen adhesion test was performed.
