Aims
- The module builds knowledge in the mechanics of dynamics and vibration, stress analysis of structures and sections, trusses and frames, mechanics of soils
- The module provides an introduction to finite element methods
Content
- Mechanics of Dynamic Systems : Undamped and damped free vibration of single degree of freedom (SDOF) systems; Equivalent stiffness and equivalent mass; SDOF systems under forced vibration, including rotation out of balance; Base excitation (undamped and damped); Response of SDOF systems to transient forcing; 2DOF systems and their forced response; Free vibration of 2DOF systems; Tuned vibration absorbers; Free 2DOF response to initial conditions; Vibration of continuous systems.
- Mechanics of Static Systems (Stress Analysis): Introduction to thin-walled and thick-walled cylinders; Thick-walled cylinders: Part yield and burst; Compound cylinders; Shear stresses in beams; Shear centre of sections; Torsion of closed and open thin-walled sections.
- Mechanics of Static Systems (Trusses and Frames): Finite Element Method for two-dimensional trusses; Continuous beams.
- Mechanics of Static Systems (Mechanics of Soils): Stresses in soils; Limit state concepts; Stress discontinuity and rotation of major stresses; Bearing capacity of a vertically loaded strip footing.
- Laboratories:
- M21 Vibration of a Single Degree of Freedom System
- M22 Static of Trusses and Beams
- M23 Stress Concentrations
Learning Outcomes
- At the end of the year the student should be able demonstrate knowledge and understanding of the theory and application of engineering mechanics
- Selection and application of appropriate analysis techniques
- Use of matrix algebra for problems in structural systems under static and dynamic loads
- Observation and recording of experimental data
- Preparation of technical reports
- The competent and safe use of laboratory equipment.
- Numerical skills
- Analytical skills
- Time and resource management.
Modes of Teaching, Learning and Assessment and how these contribute to
the learning outcomes of the module
- The courses in Mechanics are covered in lectures which are supported by problem classes and by weekly problem sheets leading to the required problem solving capability
- The topics covered in this module are analytical by nature and are assessed most effectively by timed, written examination which enables each student to demonstrate an ability to analyse and solve new problems
- One laboratory write-up will be summatively assessed
- The laboratory programme also provides formative, hands-on experience in the subject area of mechanics
- Students are able to make use of staff 'Tutorial Hours' to discuss any aspect of the module with teaching staff on a one-to-one basis. These are sign-up sessions available for up to one hour per week.
