Preface to the FraMCoS-2 proceedings by F.H. Wittmann.
FRAMCOS‑2 Conference Programme PREFACE Thirty ye訂sago， fracture mechanics was considered to be a highly interesting academic subject without any relevance for designthe ， construction， and maintenance of concrete 旬res.Few and isolated groups worked in field this and they met on the occasion of struc Il established intemational conferences on企acturemechanics such as ICF. In these big we conferences ， usually one or two sessions were devoted to concrete. ， engineers who at that time had no idea of what丘acturemechanics really Suddenly implies got fas cInated by this approach and the view was spread that civil engineering would experience a real revolution with the introduction of fracture mechanics into 加 ct町alanalysis. These expectations certainly could not and will never be satisfied. But s in this situation ， RILEM took a lead and set up a first technical committee on frac印re ・FMC).The aim originally was to present a comprehensive mechanics (RILEM TC 50 documentation on the state‑of‑the‑art (Fracture Mechanics of Concrete ， ed. F.H. Wittmann ， Elsevier (1983)) and to prep訂erecommendations on a generally accepted test 町ameters.No doubt， practically everybody method to determine fracture mechanics p expected a standardized method on how to determine KIC of concrete when this 立1itteewas set up. com ， held in Delft， It was during the first meeting of the new RILEM technical committee The Nether1ands， when Arne Hi1lerborg asked to present his ideas on frac旬remechanics in 15 minutes.
