DESCRIPTION - summary of the module content

The main aim of this module is to inform the student about the key aspects of an engineering design approach, including the development of an understanding in the areas of i) properties of engineering materials, ii) testing of material materials, iii) strength, failure and safety factor and iv) to teach numerical approaches for the prediction of stress concentration in engineering applications.

AIMS - intentions of the module

Understanding of properties of Engineering Materials and classification of Steels, Non-Iron Metals and Polymers
Understanding of physical testing of samples of materials to determine material properties
Understanding of avoiding failure in engineering applications including stress and deformation calculation
Understanding of failure mechanism including fracture and fatigue
Understanding of complex stresses and strains arising in elastic and non-elastic systems
Understanding and application of numerical evaluation methods, including both underlying principal methods and industrial software implementation
Understanding of calculation methods to assess fastening of multiple components

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

On successful completion of this module you should be able to:
