Scaling and Size Effects
Organized by
Zdeněk P. Bažant & Milan Jirásek
By now it has been
thoroughly established that softening material damage and fracture with a
non-negligible fracture process zone can cause a major non-statistical size
effect and also greatly influence the energy absorption capacity of structures.
However, randomness of defects and its consequences for structural response,
especially the size effect, are also important. The problem is multiscale, but although the multiscale
methods, currently under rapid development, are important, they give only a
part of the story because the transition between the behaviors at adjacent
scales is often spread over several orders of magnitude. Similar
behaviors are observed at very different scales and for a wide range of
materials, including many of the modern high-tech materials (concretes, ice,
ceramics, composites, biological materials, tough alloys, fatigued metals, thin
metallic films, nanocomposites, etc.). This field of
inquiry has recently advanced rapidly, and thus there is a need for exchange of
information and discussion of various new ideas. This need would be well served
by organizing a symposium on this hot subject.
