Summary, in English

Fracture in plain concrete starts normally as tensile fracture, whereby a damage zone forms perpendicular to the principal tensile stress direction. If this stress direction is maintained when the deformation within the damage zone increases, the material behaviour in the damage zone can be described by a simple stress-deformation curve. The design of a test equipment for the measurement of the material properties within a damage zone with combined tension and shear deformations is described. The design of the equipment is based on a theoretical analysis, which shows the importance of a sufficient stiffness in order to prevent rotations caused by instability. In order to fulfill the requirements on stiffness, a certain rotation in the damage zone has been accepted in the design.
