1-What is Material Toughness?
Toughness shows the ability of the material to absorb energy per unit of volume up to the point of rupture. ductile material shows a higher plastic deformation until rupture compared to the brittle material case. In other words, the ductile material can tolerate a higher energy per unit of volume than what brittle material does, or the toughness of ductile material is higher than the toughness of brittle material.
The following video lecture explains the concept of toughness comprehensively;
If we take the integral of the stress over the movement of strain from zero till rupture point, then we will achieve the toughness.
