OverviewDescriptionThis subject draws on, and brings together, the knowledge and skills developed in earlier subjects such as 48620 Fundamentals of Mechanical Engineering, 60101 Chemistry and Materials Science, and 48331 Mechanics of Solids. It also prepares students for the more dedicated design subjects to come and exposes them to practical aspects of mechanical engineering design. The objectives are that students should be able to: understand, describe and use the methodology of modelling material properties and behaviour; understand and describe the fundamental differences in the behaviour of different types of materials; understand and describe how and why things fail; realise the importance of material selection in engineering design; predict, or design to avoid, failure given the material, environment and loading conditions; and use analytical skills in stress analysis and knowledge of material properties in mechanical design. Topics include: the use of stress analysis and material properties in materials selection and mechanical design; stress analysis ? revise concept of normal and shear stress; combined stress; structures and m/c components; impact; material behaviour ? time dependent material properties; strength; failure modes ? theories, criteria for static failure (e.g. Tresca, von Mises, Mohr), fracture, creep, and fatigue; and strain energy methods.Subject objectivesUpon successful completion of this subject students should be able to:1. Describe the mechanical design process as it applies machine elements;2. Describe how and why structures and machine components fail;3. Determine the stress and strain in a machine component;4. Realise the importance of stress analysis and material selection in machine element design;5. Predict, or design to avoid, failure given the material, environment and loading conditions; and6. Use their analytical skills in stress analysis and their knowledge of material properties in mechanical design.This subject also contributes specifically to the development of the following course intended learning outcomes:Apply systems thinking to understand complex system behaviour including interactions between components and with other systems (social, cultural, legislative, environmental, business etc.) [EA Stage 1 Competency: 1.5 ] (A.5)Identify and apply relevant problem solving methodologies [EA Stage 1 Competency:1.1, 2.1, 2.2, 2.3] (B.1)Design components, systems and/or processes to meet required specifications [EA Stage 1 Competency: 1.3, 1.6, 2.1, 2.2, 2.3] (B.2)Demonstrate research skills [EA Stage 1 Competency: 1.4, 2.1] (B.6)Develop models using appropriate tools such as computer software, laboratory equipment and other devices [EA Stage 1 Competency: 2.2,2.3, 2.4] (C.2)Evaluate model applicability, accuracy and limitations [EA Stage 1 Competency: 2.1,2.2] (C.3)Communicate effectively in ways appropriate to the discipline, audience and purpose [EA Stage 1 Competency: 3.2] (E.1)Teaching and learning strategiesThis subject includes two 1.5 hour lectures per week. There are three quizzes and two lab reports.This subject is a typical 6cp subject and therefore assumes 9 hours per week, for an average student aiming to pass the subject.As a student in this subject you are expected to attend all the lectures and keep a good manner in the lecture room. You are also expected to competently organize your time and to participate actively in team work.You should understand the principles first and then follow a detailed procedure to solve the problem.You are expected to develop your critical-thinking abilities on the completion of this subject.ContentThree main topic areas are dealt with the use of stress analysis and material properties in machine element design. These are aspects of stress analysis, material properties and behaviour, and failure modes and criteria.Material behaviourMaterial properties (revision)Material selectionStrain analysisDeformation and strain in structures and machine componentsStrain energy methodsStress analysisrevise concept of normal and shear stresscombined stressstresses in structures and machine componentsimpactFailure ModesTheories/criteria for yieldFractureFatigueAssessmentAssessment task 1:Problem solving tasksIntent:Problem solving tasks that aim to evaluate the students? ability to perform stress analysis, failure analysis, and to solve impact loading and statically indeterminate problems.
