Question

Difference between ultimate tensile strength and tensile strength and fatique

Answer 1

Yield strength: When you apply some stress on a material, first it expands elastically (it will regain its original dimensions if you remove the external force), and when after a certain stress level (Yield Strength) , material deforms plastically.

Ductility: Ability of material which allows them to deform plastically under tension (into wires)

Note that ductility is phenomenon for tensionforce and malleability is corresponding term for compression force

PLEASE SORRY

Explanation:

Ratio of Tensile Stress and Tensile Strain

The ratio of tensile stress and tensile strain within elastic limit is called?
