What property of a material is a measure of its stiffness? What property of a material is a measure of its ductility? If a material is reported to have a percent elongation in a 2.0C in gage length of 2%, is it ductile?

Solution

7. Young\'s Modulus of elasticity is the property of a material that measures the stiffness of the material.

8. The properties, Elongation (Engineering strain at fracture) and Reduction of Area at fracture measure the ductility of a material.

9. Strain produced in the material = 2/100 = 0.02 and elongation = 0.02 * 2 m = 0.04m. Brittle materials have a maximum strain of 0.05 and if the strain exceeds this value, the material is said to be ductile. Thus the material in this case is a Brittle material.
