Mechanical property definition: energy absorption in the plastic range Identify the property of a material that measures its ability to absorb energy by plastic deformation before fracture. Choose the correct term.

Difficulty: Easy

Resilience
Creep
Fatigue strength
Toughness

Correct Answer: Toughness

Explanation:

Concept

Toughness = area under the entire stress–strain curve up to fracture; energy absorbed in the plastic range (and elastic range).
Resilience = energy absorbed within the elastic range only.
Creep = time-dependent deformation under constant load.
Fatigue strength = stress amplitude causing failure after many cycles.

Final Answer
Toughness
