ENGI4211: Applied Mechanics

Prerequisites

• ENGI3411 Applied Mechanics OR MEng(Overseas)

Corequisites

Excluded Combination of Modules

Aims

• This module is for students intending to fulfil the requirements of the M.Eng. streams in Mechanical Engineering (H300), Aeronautics (H420), New & Renewable Energy (H221) and General Engineering (H100).
• The module will provide graduates with advanced knowledge and understanding of computational stress analysis, dynamics, fracture mechanics and fatigue, and of methods of application to modern complex structural analysis.
• This module is complemented by the 60 credit MEng Research and Development project module or by the 40 credit Technical Project where the final year MEng student has the opportunity to apply the material taught in this module in a large scale project.
• The module provides a firm foundation for a broad range of careers in Aeronautics, Mechanical, Energy and General Engineering through an appropriate combination of core and optional courses

• Stress intensity factors and fracture toughness;
• Mechanics of the plastic zone at a crack tip in plane stress and plane strain;
• Methods of determining stress intensity factors;
• S-N approach to fatigue resistant design, including mean stress correction;
• Techniques for cumulative damage assessment;
• Macro crack growth laws and damage tolerance assessment;
• Weighted residual approach to produce FEA models;
• Theory of 8- and 20-noded hexahedral isoparametric finite elements;
• Finite element error analysis;
• Newton-Raphson scheme for non-linear analysis;
• Use of finite element programs;

Learning Outcomes

• An appreciation and technical understanding of the mechanics of sub-critical crack growth under cyclical loading and brittle fracture failure under critical conditions.
• An understanding of weighted residual approaches to development of the finite element method.
• An understanding of the fundamentals of modern computational techniques for static and dynamic stress analysis, and an appreciation of their capabilities and limitations.
• An understanding of techniques for non-linear analysis in static and dynamic stress analysis.

• An awareness of current technology, analysis methods and industrial practices along with the ability to apply those methods in novel situations.
• To use effectively specialised, advanced computational tools and packages for the analysis of stress and dynamics problems.
• The ability to carry out assessments of fatigue resistance of mechanical and structural components.
• An in-depth knowledge and understanding of specialised and advanced technical and professional skills, an ability to perform critical assessment and review and an ability to communicate the results of their own work effectively.

• Capacity for independent self-learning within the bounds of professional practice.
• Highly specialised numerical skills appropriate to an engineer.
• Highly specialised use of information technology (IT) relevant to the engineering profession.
• Mathematics relevant to the application of advanced engineering concepts.

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

• The courses in Applied Mechanics are covered in lectures, and are reinforced by seminars and by problem sheets, leading to the required problem solving capability.
• 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.
• Written timed examinations are appropriate because of the wide range of analytical, in-depth material covered in this module and to demonstrate the ability to solve advanced problems independently.
• The written examinations are supplemented by written coursework assignments based upon computational work. These written assignments provide the mechanism for the assessment of a student's ability to perform independent investigation, analysis and reporting.
