What are material selection charts?
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 four 4 basic steps in material selection process?
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.
What is material performance index?
The Material Index (M) refers to an attribute (or a combination of attributes) that characterizes the performance of a material for a given application.
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 is the Ashby method?
A useful method of doing this is by plotting them as Material Property Charts, sometimes called ‘bubble’ or ‘Ashby’ charts, with one property on one axis and another property on the other. Each material has a range of values for each property, depending on the exact composition, grade, heat treatment, supplier etc.
What are the three criteria that are important in the materials selection process?
Thus in the selection of a material: First, we decide on the requirements of the application. Second, we decide on the possible materials we can use in the application. Third, we decide what changes in the material properties are needed.
What are the three factors to be considered when choosing the right material?
Three Important Considerations
- Fabrication and Material Costs.
- Expertise Required.
- Transportation and Delivery of the Fabricated Vessel.
How is material index defined?
The material index is a measure often considered by an industrial enterprise when deciding where to locate. This index represents the ratio of the weight of local materials used in the manufacture of a product to the weight of the manufactured product in its final form.
What is the definition of material index?
The ratio of the weight of localized materials used in the manufacture of a product to the weight of the finished product. A material index much greater than 1 shows a sizeable weight loss during manufacturing.
