X-ray observation of the loaded silicate composite
Original language description
The fracture-mechanical parameter values of concrete, a quasi-brittle composite material, are determined from records of experiments on specimens with stress concentrators. One of the fracture models applicable to concrete is the double-K model. This model combines the concept of cohesive forces acting on the effective crack increment with a criterion based on the stress intensity factor. The outputs of the model are critical crack tip opening displacement and fracture toughness values, including the initiation stress intensity factor value corresponding to the beginning of stable crack propagation. In this paper, a method of calculation by means of the double-K fracture model is verified using published data and the results of a pilot wedge-splittingtest performed by the authors.
