MATL08007 2019 Engineering Materials Analysis and Testing

Preparation of material samples for defect investigation using microscopy and SEM/TEM/XRD analysis on different types of materials including ceramics, polymers, composites, metals. 

Understand material failure modes, fatigue and explore ductile-to-brittle transition effect on material impact. 

Understand the impact that chemicals and natural environmental condiitons have on material integrity and employ LCA techniques to evaluate environmental impact of materials within full product lifecycle. 

Understand structures of composite materials and calculate longitudinal modulus and strength for aligned continuous and discontinuous fibrous composites. 

Understanding typical molecular structures of polymers in respect to their physical, thermal and mechanical properties and influence of factor such as geometrical isomerism, number-average molecular weight, weight-average molecular weight, and Degree of polymerisation (DP). 

Understanding of Biomaterials and their applications in addition to gaining knowledge of the  processing of material in advanced manufacturing processes such Additive Manufacturing and non-conventional machining...

Understand principles of material selection in the context of the engineering design process.

Lectures, assignments, practical laboratory work...

Final semester exam, continuous assessment, lab work assessment., project work assessment

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 Environment: Examine the chemical reaction of the surrounding environment on the materials interacting with it.

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.

Polymer Structures: Review typical polymer molecules in terms of their chain structures, identify different molecular structures, stereoisomers, and copolymers. Examine spherulitic structures of semicrystalline polymers.

Composites: Review strengthening mechanisms for large-particle and dispersion-strengthened particle-reinforced composites. Review the different types of fiber-reinforced composites on the basis of fiber length and orientation and study the distinctive mechanical characteristics for each type.

Biomaterials: Review the application of biomaterials (metals, ceramics, polymers) that are used for implantable medical devices.. Examine their properties and composition for biocompatibility and osteointegration.

Material Processing: Review thermal processing of metal and polymers for different manufacturing processes including Additive Manufacturing, laser processing, injection moulding, casting, and forming..
