 SHE Level 4 SCQF Credit Points 20.00 ECTS Credit Points 10.00 Module Code MHH122359 Module Leader Martin MacDonald School School of Computing, Engineering and Built Environment Subject Mechanical Engineering Trimester A (September start)

### Pre-Requisite Knowledge

Engineering Design and Analysis 3

### Summary of Content

This module extends the work of the equivalent year 3 module to introduce the students to more advanced design considerations and analysis techniques and experimentatl methods for design evaluation of those problems which cannot be readily solved by means of simple formulae.

### Syllabus

The teaching syllabus will cover the following areas: Formulation for the Slope- Definition equation for flexural members. Derivation of the stiffness matrix for flexural member. Formulation of the structural stiffness and loading vectors to form system matrices. Solution of the system matrices for degrees of freedom, member loads and reactions. Analysis and synthesis of linear translation, torsional and combined (coupled) translational and torsional vibrations; with and without damping. The method of solution will be based on modelling of engineering systems and matrix methods allied to computerised solutions. Analysis and synthesis of torsional vibrations for multidegree of freedom problems including gear inertias and branching effects with and without damping, and based upon the matrix approach. The method of solution will be based on modelling of engineering systems and matrix methods allied to computerised solutions. Plastic analysis of components subject to axial and bending loads. Shape factors, plastic moment of resistance 'Mp' for symmetrical and unsymmetrical sections. Application to beam structures and determination of load factors. Residual stress and springback effects. The analysis of components containing crack-life defects using LEFM, plastic collapse and the application of the Paris Law to fatigue life prediction through crack growth analysis. Shear bending and torsional loading of components having area properties such as symmetrical and open ended and unsuymmetrical sections shear centre and warping effects. Thick Cylinders Thin and thick cylinders, basic assumptions, Lame's equations, hoop and radial stresses, closed ends, longitudinal stresses, compound cylinders and tubes, force and shrink fits, plastic yielding of thick cylinders, partial yielding, complete collapse. Integrated Product Design Studies Framework for a structured and methodical approach to product design process.

### Learning Outcomes

The expected learning outcomes are that the student should:Solve complex problems in Structural Analysis using Matrix Methods.Solve complex analysis and design problems in vibrational analysis of engineering systems using Matrix Methods.Apply the principles and techniques for fracture and fatigue analysis to appropriate engineering components.Apply the principles and techniques for plastic blending analysis to appropriate engineering components.Evaluate the effects of shear, bending and torsional loading to symmetrical and open and closed unsymmetrical cross sectional members.Apply the principles andf techniques for the analysis of thick cylinders subjected to internal and external pressure systems.Use the tools to allow the working in a design team to successfully compete an integrated design assignment

### Teaching / Learning Strategy

The material covered during lectures will be reinforced and consolidated through tutorials, seminars and practical laboratory work. Students will study and solve real world engineering problems encouraging divergent thinking and broader, deeper learning. Students will take part in practical laboratory work which will enhance data acquisition and manipulation skills, individual and group working skills, technical report writing skills and communication skills in general. Through the study of national and international engineering codes of practice, students will be global learners. Through the use of the managed learning environment GCU Learn, students will become more engaged, flexible and independent in their learning as there will be a wide range of learning resources available on line. In addition to the core module content, links to relevant databases for the sourcing of additional reading material from the current research in the subject area from around the world, and notices regarding relevant professional body talks in the local area will be made available. The assessment of the students will incorporate laboratory and design and analysis work based on real world engineering problems through group and individual coursework, and an examination. Students will receive individualised feedback on their performance through one-to-one contact with tutors at tutorials and seminars and marked coursework, which will reinforce the students' learning, and examination results.
