Sažetak
The paper assesses a possibility of implementing the notch toughness test on drawing sheets with the gauge up to 1 mm, the influence of the loading rate on the results, as well as a possibility of using this test to evaluate formability. Experiments were made on drawing steel sheets with a yield point from 145 to 250 MPa ; the notch toughness test was made with the loading rates v1 = 1.7• 10-5 ms-1, v2 = 5• 10-2 ms-1 and v3 = 4.8 ms-1. The tests have shown that reproducible results can be achieved on light-gauge drawing sheets under defined conditions. The notch toughness values, as well as the force and deformation characteristics obtained in the notch toughness test can be used to supplement and make more exact the traditional characteristics in evaluating formability at increased sheet processing speeds, which are demanded in practice.
