on the importance of selection of the right MaterialsMaterials selection is an important process within engineering and construction, especially when developing a new product or manufacturing a part or component. Selecting the appropriate type of material for the intended application is a crucial step in ensuring quality, safety and cost efficiency.
The main goal of materials selection is to put forth the most suitable material for a given job. The material should meet the end requirements for mechanics (e.g. strength and stiffness), thermodynamics (e.g. good thermal conductivity, coefficient of thermal expansion, specific heat capacity), electrical properties (e.g. conductivity, permittivity, breakdown voltage), and also cost, mass, and manufacturability. Additionally, any other necessary safety regulations must also be taken into account, such as flammability and toxicity.
A number of factors need to be taken into account when deciding on a particular material. The mechanical loadings (static, dynamic, fatigue, and creep forces) must be taken into account during materials selection, since these determine the necessary strength and stiffness properties of the material. Electrical properties must be specified for electrical components, and factors ensuring environmental compatibility must also be taken into account, such as corrosion resistance, in order to create a product that can perform reliably over a prolonged period of time without degrading or malfunctioning.
The material selection process also has to consider the availability, cost and reliability of the proposed material. The selection process should take into account the availability of the material, the cost to procure the material, and its reliability. Availability is an important factor when selecting a material, as the chosen material may not always be available on the market. Cost may also be an important consideration, as certain materials may be more expensive than others, or require specialised production techniques. Finally, reliability must also be considered, as this affects the lifetime of the material and its performance levels.
Once the suitable materials have been identified, the mechanical properties such as strength and stiffness of the material need to be assessed. This is done through a number of tests depending on the material, such as tensile tests, impact tests, fatigue tests, creep tests and fracture mechanics tests. These tests are used to ensure that the selected material has acceptable levels of performance when subjected to the mechanical loadings.
Finally, the cost of producing the parts or components from the selected material must be taken into account. Often, reducing the number of parts and simplifying the design can reduce cost. Additionally laser cutting, waterjet cutting, or other manufacturing techniques may lead to lower production costs. However, it is important to consider these costs when making the initial material selection, in order to ensure that the most cost-effective materials are chosen.
In conclusion, proper materials selection is vital in order to ensure that a product meets all the required criteria. This includes engineering properties such as strength and stiffness, thermodynamic properties such as thermal conductivity and coefficient of thermal expansion, and electrical properties such as conductivity and permittivity. Additionally, factors such as availability, cost, and reliability must be taken into account. In order to ensure that the best material for the intended purpose is chosen, tests must be carried out to assess the mechanical properties, and the availability, cost and reliability should also be considered. Proper materials selection is essential in ensuring that the product meets the requirements and performs cost effectively over a prolonged period of time.
