Discuss about impact test and DBTT, toughness, why it is important to measure impact strength or toughness.


1.Discuss about impact test and DBTT, toughness, why it is important to measure impact strength or toughness.• Materials /Equipment: Charpy V tester and AISI 1018 , a picture of the sample dimensions.• Results : charts →impact energy –temperature curves with DBTT highlighted. Comparison between parallel to the grain and perpendicular to the grain specimens in one graph .• Discussion , comment on the graphs and the fracture surfaces of the samples : either brittle or ductile fracture.• Conclusion.
