Summary

 

Design Study (Bridge) - AEM-CM23

Aims

This course is designed to be an opportunity to integrate and apply the knowledge and skills learned in the preceding lecture courses/modules.

Role

Lecturer

Materials - AE2-208

Aims

The course builds on the principles of aerospace materials, taught in first year, and expands and discusses these principles to engineering materials, particularly those employed in the aircraft industry.  The course aims to equip the student with sufficient knowledge to evaluate the balance of engineering properties required in relation to an application and to select appropriate metallic and composite materials.  The student is also made aware of the motivation for studying materials and knowledge of emerging materials for future aerospace applications.

Role

Lecturer

Impact - AEM-CM22

Aims

To describe the types of damage that can occur in laminated composites as a result of transverse impact.  To distinguish between small and large mass impact responses. To estimate the peak impact forces and delamination damage thresholds, and the properties affecting these parameters.  To review the local and overall structural response mechanisms of composite laminates after impact loading.  To identify failure mechanisms in impact damaged composites and to model their response under tensile and compressive loading.

Role

Lecturer

Introduction to Composites (FRP) - AEM-CM01

Aims

To provide an overview of the science, technology and application of composite materials.

Role

Lecturer

Materials in Action - AE3-408

Aims

The aims of this course are to outline the procedures necessary to select a material for a given purpose.
•    To define the purpose of the item chosen for design.
•    To specify the operating regime (loads, environment etc.) of the chosen item.
•    To calculate the stresses and strains caused by the operating regime.
•    To list the relevant properties (chemical, physical, mechanical etc.) of candidate materials.
•    To consider environmental factors during the material selection process
•    To teach methods for materials selection under conflicting requirements and penalty functions
•    To list possible selection criteria and choose the criterion most appropriate to the circumstances.
•    To consider the effect of shape when selecting a material
•    To evaluate the candidate materials against the selected criteria.
•    To use ideas and principles from other lecture courses as an essential part of selecting a material.
•    To teach advanced issues regarding polymer composites, including failure
•    To present an overview of new and emerging materials, including nanomaterials and multifunctionality.
•    To teach the mechanics of cellular solids and design with sandwich structures
•    To teach on structural health monitoring of aerospace materials
•    To introduce non-destructive evaluation techniques for aerospace materials

Role

Lecturer

Stiffness and Strength - AEM-CM09

Aims

  • Introduce micromechanics concepts & use in calculating stiffness/strength.
  • Restricted to fibre / polymer matrix composites
  • Short fibre lectures concerned with fibres up to 50mm in length
  • Compare short fibre composites with competitive materials
  • Highlight problems associated with the design of products from short fibre composites
  • Suggest possible analyses for predicting stiffness and stiffness and strength
