(b) highest stress a material can experience without permanent deformation

(c) average stress experienced by material in its lifeline.

(d) strain on material

The question was asked in homework.

I want to ask this question from Aircraft Materials topic in section Testing Aircraft Materials of Aerospace Materials & Processes

Answer 1

Correct option is (b) highest stress a material can experience without permanent deformation

To explain: The elastic limit is the highest stress that a material can withstand, without permanent deformation present when the stress is released completely. It is not the lowest amount of stress present.
