An intensive internal material damage evolution precedes a failure in quasi-brittle materials. Not only the existence of damage but also its quantification and the geomet [...]

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

Undesirable energy dissipation taking place during wedge-splitting tests on cementitious composites and resulting in overestimation of the values of the determined fractu [...]

The paper introduces a methodology for an estimation of the size and shape of a fracture process zone evolving at the macroscopic crack tip in quasibrittle materials duri [...]

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 [...]

Values of fracture parameters of quasi-brittle building materials are usually determined from results of tests performed on notched testing specimens. The paper focuses o [...]

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 [...]

Three point bending test of central notched specimen is used for determination of fracture properties of concrete, mortar and hardened cement paste. The properties – e. [...]

Selected experimental results from static loading tests of pre-tensioned railway sleepers and results of numerical simulations of the test are presented in this paper. Th [...]

The paper presents a numerical study of the mechanical response of pre-stressed monoblock railway sleepers. The investigation of the structural behaviour is performed via [...]
