improvement of strength and impact toughness for cold

How are strength and toughness related to fatigue?How are strength and toughness related to fatigue?Takeaway For structural components exposed to fatigue conditions, designers must be concerned with both the strength and the toughness. Strength is a measure of the stress that a crack-free metal can bear before deforming or breaking under a single applied load.What is the Difference Between Strength and Toughness? How is impact strength related to static compressive strength?How is impact strength related to static compressive strength?There is no unique relation between the im­pact strength and the static compressive strength of concrete. Thus to assess the impact strength, the principal criteria was considered as the ability of concrete specimen to withstand the repeated blows and to absorb energy.Strength of Concrete Tensile and Fatigue Concrete Technology Improvement of strength and toughness of SKD11 type cold improvement of strength and impact toughness for cold

The strength and toughness of a newly developed 0.8C-8Cr cold work tool steel whose composition was controlled to suppress the precipitation of massive eutectic M 7 C 3 carbides were investigated with reference to microstructure and were compared with conventional SKD11. The toughness was evaluated by the area under the stress-strain curve.
