'The present volume, which summarizes the recent results, is thus a very welcome addition to the literature. ...presents an outstanding exposition of the current research and the latest results. ...highly recommended to researchers, teachers, and graduate students in the field of fracture mechanics, and it should prove useful to concrete engineers as well.'
