Brief Handbook Description: | BMET5944 equips students with the state-of-the-art knowledge about the design and development of new generations of multifunctional materials by learning from nature. The course covers: (a) the construction, deformation and failure behaviour of hard and soft natural materials which confer them with outstanding mechanical properties and multi-functionalities such as shape-morphing, self-healing and damage sensing, (b) the fabrication techniques to implement similar principles in engineering materials in order to improve their performance, (c) the theoretical and experimental approaches to study the mechanics of resulting materials, and (d) examples of bioinspired materials in industries, current challenges of the field and future perspectives. |
Assumed Knowledge: | 1000-level materials science and mechanics. |
Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.
Attribute Development Method | Attribute Developed |
During the lecture and tutorials, the students will learn how to use and drive equations to explain the mechanics of natural materials that are usually composites of hard and soft phases. The students will also learn about simple fracture mechanics to explain why natural materials are tougher than their constituents. | (1) Maths/ Science Methods and Tools (Level 3) |
The students will develop a deep understanding of the structure-performance relationships in biological and bio-inspired materials. | (2) Engineering/ IT Specialisation (Level 3) |
During the lectures/tutorials, we will always ask students about their ideas on how to solve a challenge before introducing the solution. In the assignments, team presentation, and exams, we will ask questions that will promote the problem-solving ability of the students. The student will be familiarized with some of the innovative (and sometime quite simple) techniques to solve challenging problems in engineering and science. | (3) Problem Solving and Inventiveness (Level 3) |
The students will learn that development of novel bio-inspired materials requires knowledge in biology, materials science and mechanics and will learn about all these during the lectures and tutorials. | (5) Interdisciplinary, Inclusiveness, Influence (Level 3) |
Their research skills will be improved by working on the final project on a subject of their interest relevant to bioinspiration. | (6) Communication and Inquiry/ Research (Level 3) |
The students will practice effective communication in their group assessments and presentation to the class. | (7) Project and Team Skills (Level 3) |
For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table 2018.
Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.
