What is material selection process?

What is material selection process?

Material selection is the act of choosing the material best suited to achieve the requirements of a given application. Many different factors go into determining the selection requirements, such as mechanical properties, chemical properties, physical properties, electrical properties and cost.

What are the four steps in the strategy of materials selection in mechanical design?

The process for selecting materials and the process for selecting the manufacturing process involves four main steps in the order: translation, screening, ranking and supporting information.

What are the common materials used in mechanical engineering design?

Engineering Materials

  • Ferrous Alloys. Carbon Steel. Low-Alloy Steel. Tool Steel. Stainless Steel. Cast Iron.
  • Aluminum Alloys.
  • Nickel Alloys.
  • Copper Alloys.
  • Titanium Alloys.

What are physical and mechanical properties?

Physical properties are things that are measurable. Those are things like density, melting point, conductivity, coefficient of expansion, etc. Mechanical properties are how the metal performs when different forces are applied to them. That includes things like strength, ductility, wear resistance, etc.

What is material selection chart?

Materials selection charts are used to screen out materials which do not meet the design constraints, and materials indices are used for ranking the shortlisted materials in order of excellence.

What are the material selection parameters?

Some of the important characteristics of materials are : strength, durability, flexibility, weight, resistance to heat and corrosion, ability to cast, welded or hardened, machinability, electrical conductivity, etc.

How are materials selection used in mechanical design?

Materials Selection in Mechanical Design, Fifth Edition, winner of a 2018 Textbook Excellence Award (Texty), describes the procedures for material selection in mechanical design in order to ensure that the most suitable materials for a given application are identified from the full range of materials and section shapes available.

Is the book materials selection in Mechanical Design copyrighted?

Although the book itself is copyrighted, the reader is authorized to make unlimited copies of the charts, and to reproduce these, with proper reference to their source, as he or she wishes.

How is shape selection related to material selection?

Material and Shape Selection ‰Performance isn’t just about materials – shape can also play an important role ‰Shape can be optimized to maximize performance for a given loading condition ‰Simple cross-sectional geometries are not always optimal ƒEfficient Shapes like I-beams, tubes can be better ‰Shape is limited by material

How are the properties of materials used in engineering?

Understanding materials, their properties and behavior is fundamental to engineering design, and a key application of materials science.
