Solve this multiple-choice question and choose the correct option.

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 AnswerToughness

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 AnswerToughness
