The problem of the crack emanating from the interphase region of the circular inclusion is investigated. The problem combines an application of dislocation distribution t [...]

The paper reports on the determination of basic mechanical material parameters of several concrete and alkali activated concrete and fly ash mixtures intended for the co [...]

The fracture-mechanical parameter values of concrete, a quasi-brittle composite material, are determined from records of experiments on specimens with stress concentrator [...]

Concrete is represented as a two-phase material in this paper. Behaviour of a single macrocrack approaching to the interface between hardened cement paste (matrix) and ag [...]

The paper presents the influence of the various concrete mixtures on fatigue parameters measured on three-point bending specimens. These specimens are the most frequently [...]

Procedure for estimation of fracture process zone size of concrete as value of characteristic length which quantifies intrinsic brittleness of the material is presented i [...]

An influence of the test specimens preparation – shape and width of a stress concentrator – on the values of parameters of nonlinear fracture models of quasi-brittle [...]

The paper presents the influence of the various notch depths for the range of starting notch width on a crack initiation in three-point bending specimens. These specimens [...]

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 [...]

The knowledge of fracture-mechanical parameters is fundamental for failure modelling of concrete structures. Problems of the true fracture energy of this quasi-brittle ma [...]
