Effect of Softening Function Type in the Double-K Fracture Model: Concrete Specimens with and without Fibres
Original language description
Cement-based composites are traditionally a commonly used material in civil engineering structures. The basic representative of this type of material is concrete, a quasi-brittle composite in which crack resistance can be achieved by the addition of fibres. The double-K fracture model can be used to calculate the fracture-mechanical parameter values of structural concrete with and without polypropylene fibres. This model combines the concept of cohesive forces acting on the crack length with a criterionbased on the stress intensity factor, using a 'softening function' to determine the cohesive part of fracture toughness. In this paper, authors determine the effect of the type of this softening function on the evaluation of fracture tests performed onsets of concrete specimens with and without polypropylene fibres.
