“…The results also show a "twilight velocity zone" in which the neck is located in the notch (specimens [11][12][13][14], and this zone covers both the lower and higher velocities applied in the tests. These specimens do not reveal a specific pattern.…”

“…The understanding and documentation of dynamic stress concentration factors has been considered an important field for many areas of mechanical engineering, including crashworthiness, high-speed impact, and transportation of hazardous materials [12]. Experimental [13,14] and numerical [12,15] techniques have been used to analyze the influence of notch geometry and loading conditions on the differences between quasi-static and dynamic elastic stress concentration factors.…”

Dynamic Necking of Notched Tensile Bars: An Experimental Study

The mechanics of necking inception in dynamically-stretched notched specimens have been investigated. For that task, a systematic experimental campaign of quasi-static and dynamic tensile tests on martensitic steel specimens has been conducted. Samples with and without notches have been considered. Unlike the quasi-static tests, the dynamically-tested notched samples revealed that, under certain loading conditions, flow localization may develop away from the groove. The experimental results presented in this investigation show that the presence of sharp geometrical imperfections in ductile materials subjected to dynamic loading does not necessarily dictate the necking and fracture locus.
