ABSTRACT
This can be a good method for case study development, as locating resources for the case study is easier and the lecturer’s in-depth knowledge and interest in the topic will add to the students’ case study experience. Examples of this approach are given below:
These case studies were developed from the lecturer’s research interests in polymeric foams following many years working in this field. The case study topics are: flexible foams that cushion falls (e.g. sport crash mats, etc.), closedcell polystyrene and polypropylene foams for packaging and foam cushions for wheelchairs. The case studies are run over multiple sessions with supporting lectures and content provided on a dedicated website developed by Dr Nigel Mills from the University of Birmingham (www.foamstudies.bham.ac.uk). Each topic on the website contains background information, videos, design programmes, laboratory experiments, links to other websites and interactive tests. Videos from high-speed photography, or from finite element analysis computation, are used to illustrate the effects of loading on complex foam geometries. The students understanding of foam mechanics and structure (density, polymer, open or closed cells) are tested and simple virtual experiments can be performed to validate the materials design process. The case studies provide added value to the students’ learning experience as they involve areas of current research developed by a world expert in that subject.
