436-222 Design and Materials 1 - Environmental

Students should be familiar with material covered in 436-101 Engineering Mechanics and Materials, 436-105 Engineering Communications and 100-level mathematics.

Unit 1, Engineering Design: Students should gain skill in designing simple engineering components for the structural integrity of environmental systems, be confident with practical work formulated in a graded progression from well-delineated problems to dealing with complex and/or vaguely defined design tasks in environmental areas.

Topics include failure modes for engineering systems, failure predictors for engineering components under multi-axial stress conditions; rational assessment of safety factors and maximum credible accident; integrity of structures and machines, design against failure; modelling of complex load-bearing systems in terms of simple engineering components; design of elements of structures and machines from first principles; design to resist fatigue, axial tension and compression, combined torsion and bending and internal pressure (only common metallic materials are considered); design of bolted and welded joints; and approaches to uncertainty in design problems, particularly those related to the environment.

Unit 2, Engineering Materials: Students should develop further understanding of materials, aided by laboratory exercises based on topics covered in 436-101 Engineering Mechanics and Materials.

Topics covered include dislocations and their relevance to plastic flow; particulate and fibre-reinforced composite materials; recovery, recrystallisation and grain growth in metals; creep; static and dynamic fatigue; and friction and wear.

Assignments, laboratory and technical reports not exceeding 50 pages or equivalent; participation in oral presentations and seminars; two examinations not exceeding two hours each. Completion and submission of satisfactory laboratory reports and assignments is a prerequisite for admission to the written examination. Students will be notified of the weighting of assessment components at the beginning of semester.
