Which is more ductile in stress strain curve?

(b) Material A is more ductile, because it has a greater plastic region (from elastic limit P to breaking point Q) than material B.

What determines the ductility of a material?

The ability of a material to deform plastically without fracturing is called ductility. In the materials usually machined in our shops, ductility is measured by determining the percent of elongation and the percent reduction of area on a specimen during a tensile test.

How do you determine ductility?

There are two measures required when calculating ductility:

1. Elongation. The increase in the gage length of the material, being subjected to tensile forces, divided by the original gage length.
2. The reduction of the cross sectional area.
3. Gage length.
4. Specimen dimensions.
5. Test speed or strain rate.

How do you know if a material is ductile or brittle from stress strain?

Brittle and Ductile Materials Typically brittle materials have a fracture strain less than 0.05 (∊f < 0.05) and ductile materials have a fracture strain greater than or equal to 0.05 (∊f ≥ 0.05).

Which is more ductile A or B?

material B is more ductile.

What is steel ductility?

Ductility of Steel A material that can bend and deform easily without fracturing is more ductile, while a brittle material is less so. Iron on its own is a ductile metal, which limits its usability for larger projects. By alloying iron with carbon, the resulting steel has less ductility and greater tensile strength.

What factor increases ductility?

Which factor increases ductility? Explanation: Annealing process reduces stress inside the structure. Thus ductility of material increases. Cold working, alloying and the presence of inclusions reduce the ductility of materials.

What are the factors affecting ductility?

Factors that Affect Ductility of Metals: Ductility is affected by intrinsic factors like composition, grain size, cell structure etc., as well as by external factors like hydrostatic pressure, temperature, plastic deformation already suffered etc.

What is ductility material?

Ductility is the ability of a material to sustain a large permanent deformation under a tensile load up to the point of fracture, or the relative ability of a material to be stretched plastically at room temperature without fracturing.

What is ductility name some very ductile metal?

Ductility is the physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking. A ductile substance can be drawn into a wire. Examples: Most metals are good examples of ductile materials, including gold, silver, copper, erbium, terbium, and samarium.

Which has more ductility?

The most ductile metal is platinum and the most malleable metal is gold.
