Thickness effect on cleavage fracture of ferritic sheet during in-plane impact tests

The in-plane impact test on non-standard samples limited by original materials is essential in assessing crack resistance due to its emersion of realistic stress conditions. The thickness effect on fracturing behaviors and crack resistances was investigated, based on Fe-3Si-0.9Al non-oriented silicon steel, one kind of brittle ferritic sheets. The “V-notch” impact samples with different thicknesses were obtained alternately with uniform...
