Journal of Metals, Materials and Minerals

Publication Date



The paper analyzes the influence of the loading rate in the interval from 1 to 1000 mm/min on the mechanical properties of drawing quality steel sheet with the gauge of 1 mm, used for the manufacturing of automotive parts, under tension and bending conditions. It describes the aspects of material characteristics under tension and bending conditions, while bending tests were made on notched specimens (a modified impact bending test). The paper presents knowledge that using a modified notch toughness test. It is possible to achieve the pressability (formability) characteristics corresponding to dynamic strain rates even under the static loading.
