Reference: AQA, OCR
The point beyond which the material no longer returns to its original length.
The maximum force beyond which the material does not return to its original length when the force is removed, resulting in permanent deformation.
The point up to which the material obeys Hooke's law, with stress proportional to strain, and beyond which permanent deformation starts.
The limit within which E applies, where stress is proportional to strain.
