What is Toughness

2  · Toughness is the ability of a material to absorb energy and plastically deform without fracturing. One definition of toughness (for high-strain rate, fracture toughness) is that it is a property that is indicative of a material''s resistance to fracture when a crack (or other stress-concentrating defect) is present.Toughness is typically measured by the Charpy test or the …
