The IUT AM Symposium on Microstructure Property Interactions in Composite Ma- rials was held during the dates 22nd to 25th August 1994 in Rebild Bakker Conference Centre, situated in the heart of one of Denmark's most beautiful natural areas. Participation in the Symposium was reserved for invited participants, suggested by members of the Scientific Committee. The cooperation with the Scientific Committee is highly appreciated. The Symposium brought together 76 researchers from 15 countries representing a broad range of backgrounds relevant to the topic of the meeting. The participants represented the disciplines of materials science and engineering, applied mechanics, applied mathematics and scientific computations. The Symposium comprehensively addressed the analytical, numerical and experimental methods that provide an estimation of the overall, effective properties from microstructural data. The 41 contributions emphasized the significance of the microstructure morphology in understanding the nature and origin of a multitude of properties such as viscoelasticity, plasticity, strength and fracture for a variety of polymer, metal and ceramic based composite materials. Specifically, the Symposium examined and reviewed the current state of the art of micromechanical modelling, experimental investigations and morphological qu- tification of composite materials' microstructure. The volume contains 35 papers published in an alphabetic order after the name of the first author. Much to regret of the Scientific Committee some manuscripts were not submitted. The financial support of the IUT AM, the Obels Family Foundation and the Institute of Mechanical Engineering, Aalborg University, is gratefully acknowledged.

Klappentext

This volume contains 35 contributions presented at the IUTAM Symposium on Microstructure--Property Interactions in Composite Materials. The subject of the Symposium was the quantitative description of microstructures and linking this description to physical properties of composite material systems. The contributions emphasized the significance of the microstructure morphology in understanding the nature and origin of a multitude of properties, such as viscoelasticity, plasticity, strength and fracture for a variety of polymer, metal and ceramic-based composites. The volume will be of interest to specialists in the mechanics of solids, materials scientists and engineers investigating the use of advanced materials in structural applications.
