| DESCRIPTION | This study-unit gives an insight into the following topics: - Structural Integrity assessment using a Design by Analysis approach. - Theoretical study on the phenomenon of buckling using both an analytical and a numerical approach. - Eigenvalue buckling. - The effect of shape imperfections on the buckling load. - Description of the high cycle fatigue phenomenon. - Fatigue of welded and unwelded material. - Details of how to perform buckling and high cycle fatigue assessments following the European code EN13445 Part 3. Most knowledge gained in the study-units of Mechanics of Materials is necessary background to the area of stress analysis and structural integrity assessments but fails to address the analysis of complicated real life components. This unit on Structural integrity bridges the gap between theory and real life design. Students will be provided with the necessary classical background theory necessary to understand the two different failure modes. Due to the nature of the study unit, tuition is necessary to teach the student background theory, but this will be complemented with significant, independent problem solving and FEA software application. A review of the underlying FEA theoretical basis may sometimes also be given. The software will be utilized to further develop the knowledge and understanding developed while studying the classical background theory and apply them to case studies. Study-unit Aims: The main aim of this study-unit is to help the student consolidate knowledge gained in the study units of Mechanics of Materials and finite element analysis with real life applications that require an instability/buckling assessment and/or a fatigue assessment. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - Describe eigenvalue buckling,elastic buckling and plastic buckling behaviour and take into account the role played in buckling when shape imperfections are present in a component; - Utilise empirical formulae for the design of struts/columns; - Make use of energy methods in the design of struts, plates and shells under the action of compressive stresses; - Describe the procedure required to perform a fatigue assessment; - Distinguish between the S-N approach and the Fracture Mechanics approach for fatigue life prediction of components; - Apply different methods for fatigue assessment of welded and unwelded material; - Apply finite element software and codes of standards to perform buckling and fatigue assessments of mechanical components. 2. Skills: By the end of the study-unit the student will be able to: - Perform a Buckling and Instability analysis using analytical methods for straightforward applications and using finite element analysis for real applications; - Perform a Fatigue assessment of welded and unwelded components using analytical methods for straightforward applications and using finite element analysis for real applications.
