| DESCRIPTION | This study-unit builds up on the engineering applications encountered in Mechanics of Materials 1. It places an emphasis on the solution of the equilibrium, compatibility of deformation and constitutive equations in order to solve certain indeterminate problems in the field of Mechanics of Materials. This study-unit gives an insight into the following topics: - Transformation of stress and strain into different directions and acting on different planes; - Theories of elastic failure, Maximum stress, Tresca, von Mises; - Euler's buckling equations and energy methods to analyse struts under compression; - Energy methods (Castigliano's & virtual work) to analyse indeterminate structures; - Limit analysis; - Thick walled cylinders and rotating disks; - Design of riveted, bolted and welded joints; - Design of thin rectangular and circular plates; - Hertz contact stress equations. Study-Unit Aims: The aims of this study-unit are mainly to advance the knowledge of Mechanics of Materials in the area of statically indeterminate problems, to help the student appreciate the difference between elastic and inelastic analysis and to introduce the idea of solving mechanics of materials problems using different approaches such as energy methods and using the theory of elasticity approach. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - Identify electrical resistance strain gauges to measure shear strain, bending strain and tensile/compressive strain; - Define a number of theories of elastic failure; - Establish energy methods to analyse struts under compression and indeterminate structures; - Describe the use of limit analysis; - Define the theory behind thick walled cylinders and rotating disks; - Identify how riveted, bolted and welded joints are designed; - Prescribe equations necessary for the design of thin rectangular and circular plates; - Describe the Hertz contact stress equations. 2. Skills: By the end of the study-unit the student will be able to: - Use electrical resistance strain gauges to measure shear strain, bending strain and tensile/compressive strain; - Use theories of elastic failure to design mechanical engineering components; - Use energy methods to analyse struts under compression and indeterminate structures; - Use limit analysis in design; - Design thick walled cylinders and rotating disks; - Design riveted, bolted and welded joints; - Design thin rectangular and circular plates; - Use the Hertz contact stress equations in contact stress analyses.
