This was a 4th year module which has now been amalgamated with other modules. However the material it covered is tangentially related to the topic of fluid mechanics - it concerns another branch of continuum mechanics, the study of stress and strain in solid bodies. Contained in this part of the site are lecture notes for the course, and MathCad worksheets illustrating aspects of the material. Lecture notes Lecture 1 - Introduction Lecture 2 - More about Stress Lecture 3 - 2d solutions - Cartesian coordinates Lecture 4 - 2d solutions - Polar coordinates Lecture 5 - 2d solutions - displacements Lecture 6 - Linear Elasticity Lecture 7 - Torsion Lecture 8 - Energy methods Lecture 9 - Linear Elastic Fracture Mechanics Lecture 10 - Complex Variable Methods MathCad Worksheets Worksheet about Stress Tensor (MathCad7 version) Worksheet about the biharmonic equation (MathCad7 version)
