ABSTRACT
The present project is part of a major fracture-mechanics project which has been going on since 1974 . The project has resulted in the development of the Fictitious Crack Model (FCM), Hillerborg (1989-a), which has become the principal model regarding fracture-mechanics analyses at the Division of Building Materials, Lund Institute of Technology. The goal of this particular project has been to determine material properties which are necessary for mixed mode I and II fracture-mechanics applications of FCM.
