Learning Outcomes 3.2

3.2: Identify the required properties for the product and select the most appropriate materials and processing methods

 

  1. For the Chosen product, identify appropriate materials used for its manufacture and the appropriate mechanical and thermal properties of these materials and discuss them in details.

(Maximum length 400 words)

 

  1. Identify and discuss three of the appropriate processes used in the manufacture of the chosen product.

(Maximum length 400 words)

 

 

Learning Outcomes 3.3

3.3: Identify and explain the possible limitations on the product imposed by the processing and by the need to safeguard the environment and minimise costs

 

  1. Manufacturing processes may impose limitation on the manufactured product. List the main possible limitations and choose three from the list to discuss their influence on the function of the product and suggest ways to safeguard environment and minimise costs.

Learning Outcome 4.1

4.1: Explain the common causes of in-service failure for products or structures produced from each or a combination of the four categories of engineering materials

 

  1. Choose one product or a structure made from any one of the four categories of materials (metal, ceramic, polymer or composite) or in combination and examine and discuss three of the most common causes of its failure such as wear and tear, creep, fatigue, impact, overstressing, corrosion, temperature, thermal cycling, residual stresses, stress relaxation, degradation, radiation or electrical breakdown.

Learning Outcomes 4.3

4.3: Explain the methods for investigating materials failure and for estimating product service life, when a product is subject to creep and fatigue loading

 

  1. Identify three main causes of service failure for the chosen product and discuss each in detail.

(Maximum length 300 words)

 

  1. For the chosen product explain how its service life can be estimated when it is subject to creep and fatigue loading.

(Maximum length 300 words)

 

 

Learning Outcomes 4.4

4.4: Determine and make recommendations for remedial/preventative measures for a given product or materials structure that will help improve its service life

 

  1. For the chosen product suggest three ways of improving it’s service life and discuss the measures that need taking in order to overcome the causes of service failure.
