DESCRIPTION - summary of the module content
AIMS - intentions of the module
This module introduces more advanced aspects of theory of elasticity as applied to solid mechanics, providing a basis for study in Solid Mechanics, Computational Engineering and Materials. It then introduces and develops experimental stress analysis, techniques for global and localised strain and stress measurement, and data analysis. It applies these to study of fracture and failure behaviour of materials and in the application of analytical techniques to problems of fracture mechanics.
