On the fractal dimension of fracture surfaces of concrete elements
- 128 Downloads
The problem of the relation between the fractal dimension of a fractured surface and the fracture toughness expressed by the stress intensity factor is investigated. The theoretical conditions for such assumptions are discussed. Collected experimental results and new tests performed onconcrete specimens subjected to Mode II fracture seem to confirm that relation within the scope of materials tested and with certain necessary restrictions.
