A discussion of strain-softening in concrete
The question of whether concrete strain-hardening is a real material property is discussed here. The discussion is given from both the physical and analytical point of view. New evaluations of the actual nature of strain-softening are added to those existing in literature. A concrete specimen under uniaxial monotonic compression in displacement-control is characterised by load (N)-displacement (u) diagrams with softening. During loading, the specimen exhibits a crack propagation pattern depending on its structural nature of the specimen and interaction with the test machine. The N-u diagram itself is affected by the structural nature of the specimen and interaction, since crack propagation modifies the resistant structure.
