MATL08006 2019 Engineering Materials Analysis and Testing

Employ Ashby's materials selection charts for the development of material indices and use these to select the most appropriate material for engineering applications.

Assess and choose the most appropriate heat treatment method for hardenability of part and surface hardness.

Select the most appropriate materials for tooling applications. 

Demonstrate understanding of material failure modes, fatigue and explore the ductile‑to‑brittle transition effect on material impact.

Demonstrate an understanding of typical molecular structures of polymers in respect to their physical, thermal and mechanical properties.  This will include the influence of factor such as geometrical isomerism, number‑average molecular weight, weight‑average molecular weight, and degree of polymerisation (DP).

Demonstrate an understanding of biomaterials and their applications, in addition to applying knowledge of the processing of materials in advanced manufacturing processes such Additive Manufacturing and non‑conventional machining.

Fulltime
The theoretical and background material will be presented through a series of lectures. Application of the theory will be demonstrated in class and understanding demonstrated through ongoing laboratory sessions.

Online
This module will be delivered using blended learning techniques. The theoretical and background material will be presented through a series of online lectures. Application of the theory will be demonstrated through an end of semester laboratory session.

Students will attend practical laboratory sessions and write reports on materials tests carried out.

Students will sit a terminal exam.

Repeat assessment may require a written exam and/or resubmission of laboratory reports as by the lecturer in charge.
 

Material Defects: Review material defects present in polymers, ceramics and metals. Measure the quantity of these defects that are likely to be present. Fatigue analysis and deflection on materials also will be examined in both lab and lecture.

Material and Production: Examine the forces, power and energy requirements for different material production techniques such as rolling, forging, extrusion and drawing. 

Life Cycle Analysis: Review the life cycle analysis technique and apply it to different products for different material options.

Material Selection: Review Ashby's model for material selection and examine this model for different material applications such as tool steels.

Heat Treatment: Understand and evaluate the different heat treatment mechanisms for hardness and hardenability

Materials Testing: lab tests for fatigue, torsion, melt flow index, heat treatment and non destructive testing.
