The materials dealt with in this volume include wood, concrete, various metals, composites, ceramics, and porous geological media. Obviously, the properties and serviceability of such materials vary widely, and an almost universal theme in their testing is that the properties depend on the scale at which the analysis or observation is made. At each scale, `probability' plays an important role, where the word `probability' is used in a wider sense than the classical one.
The book begins with a review of progress over recent years, identifying key questions that remain open. One point is how to observe/measure material properties at different scales, and whether a probabilistic approach, at each scale, is always applicable and advantageous. Obstacles to the identification of a universal approach include the wide range of materials and the diversity of applications.
The hierarchical nature of materials and implications for modelling, testing and application are discussed extensively. Modern mathematical tools show considerable promise in attacking the multiscale nature of materials in modelling and testing, such as wavelet analysis, intersection methods for random sets, and truncated series expansion of random fields. Multiscaling is also discussed in the context of nonlinear dynamics. Furthermore, the concepts of scaling and criticality and their applicability in materials science create interesting points of view.
Most contributions present both experimental and analytical/numerical results. A few are purely theoretical, and some are purely numerical.
There are numerous technological materials - such as metals, polymers, ceramics, concrete, and many others - that vary in properties and serviceability. However, the almost universal common theme to most real materials is that their properties depend on the scale at which the analysis or observation takes place and at each scale "probabilities" play an important role. Here the word "probabilities" is used in a wider than the classical sense. In order to increase the efficiency and serviceability of these materials, researchers from NATO, CP and other countries were brought together to exchange knowledge and develop avenues for progress and applications in the st 21 century. The workshop began by reviewing progress in the subject area over the past few years and by identifying key questions that remain open. One point was how to observe/measure material properties at different scales and whether a probabilistic approach, at each scale, was always applicable and advantageous. The wide range of materials, from wood to advanced metals and from concrete to complex advanced composites, and the diversity of applications, e.g. fatigue, fracture, deformation, etc., were recognized as "obstacles" in identifying a "universal" approach.
