Toughness

|
In materials science and metallurgy, toughness is the resistance to fracture of a material when suddenly stressed. It is defined as the amount of energy that a material can absorb before breaking, and can be found by finding the area (i.e., by taking the integral) underneath the stress-strain curve.
