Prediction of vibration and thermal behaviour of an automotive exhaust manifold: a comparative study

Abstract

"ISSN: 1743-3533 (on-line)."--Title page verso. Conference proceedings. Containing papers presented at the Seventh International Conference on Materials Characterisation, this book presents the latest advances in a rapidly developing field that requires the application of a combination of numerical and experimental methods. The work has been contributed by researchers who use computational methods, those who perform experiments, and those who combine both. Materials characterisation is important to ensuring that new products meet the needs of industry and consumers. The accurate characterisation of the physical and chemical properties of the materials requires the application of both experimental techniques and computer simulation methods. The wide range of materials now available, from metals to polymers and semiconductors to composites, necessitates a variety of experimental techniques and numerical methods. The papers in the book examine various combinations of techniques. The papers cover such topics as: Cementitious materials; Computational models and experiments; Corrosion problems; Advances in composites; Micro and macro materials characterisation; Fracture and fatigue problems; Mechanical characterisation and testing; Recycled materials; Structural health monitoring; Energy materials.
