Material Properties & Processing

What property is defined as a material's resistance to permanent (plastic) deformation, typically reported as yield strength?

On an engineering stress-strain curve, what does the slope of the initial linear elastic region represent?

What is the name for the stress at which a material begins to deform plastically, often found by the 0.2% offset method?

What measure of ductility expresses the change in gauge length at fracture relative to the original length?

How is ductility characterized for a material, and which two common measures quantify it?

What material property is defined as the energy absorbed per unit volume up to fracture, represented by the area under the stress-strain curve?
