How do you select material for mechanical design?

Best Practices for Choosing Materials

  1. Understand the critical components of your design. The first step in the process of choosing the right material is to understand which structural elements are most important for the mechanical integrity of your product. …
  2. Know your materials. …
  3. Validate your mechanical design.

What is the most common materials properties required in any engineering design requirement?

1) Hardness Hardness is one of the most commonly used material properties, and can be applied to any solid material. It refers to the ability of a material to withstand scratching or indenting on its surface. Obviously, harder materials are more difficult to scratch or dent.

What is classification of engineering materials?

The engineering materials can broadly be classified as: a) Ferrous Metals b) Non-ferrous Metals (aluminum, magnesium, copper, nickel, titanium) c) Plastics (thermoplastics, thermosets) d) Ceramics and Diamond e) Composite Materials & f) Nano-materials.

What is material and its types?

Traditionally the three major classes of materials are metals, polymers, and ceramics. Examples of these are steel, cloth, and pottery. These classes usually have quite different sources, characteristics, and applications.

What are the applications of engineering materials?

These are used in packing, insulating materials, covers, etc. Example: Cotton, Nylon, Terylene, PVC, etc. Composites are the mixture of materials like metals and alloys and ceramics, metals and organic polymers, ceramics and organic polymers. These are used in electrical devices and airplane parts.

What are the classification of materials?

Solid materials have been conveniently grouped into three basic classifications: metals, ceramics, and polymers. This scheme is based primarily on chemical makeup and atomic structure, and most materials fall into one distinct grouping or another, although there are some intermediates.

What are the different methods of classification of materials?

These three classifications are metallic, ceramic and polymeric. Additionally, different materials can be combined to create a composite material. Within each of these classifications, materials are often further organized into groups based on their chemical composition or certain physical or mechanical properties.

What are the five basic elements of material selection for product design?

The materials selection process for a component or joint between components involves these steps:

  • Identify the design requirements.
  • Identify the materials selection criteria.
  • Identify candidate materials.
  • Evaluate candidate materials.
  • Select materials.

Which metal is mainly used in preparation of machinery?

Stainless Steel One of the most widely used metals for machining purposes today is stainless steel. Although it’s very popular, it may be hard to machine due to its intense strength and hardness.

How do you decide what material to use?

Start with a Bill of Materials (BOM) to know how many materials your product will use. Identify the material requirements including performance, aesthetics and cost. Prototype and test using different materials and manufacturing techniques. Evaluate the results and find the materials that satisfy the product’s needs.

How do we choose a material to make an object?

We choose a material to make an object depending on its properties, and the purpose for which the object is to be used.
