For application in civil engineering structures and also for strengthening existing structures cement-based composites are one of the most frequently used materials. Although many studies have been conducted on the mechanical ...

Durability and sustainability of structures made from concrete like materials is getting more into an interest of civil engineers. Structures are subjected not only to uniaxial load, this means if there is a crack inside ...

This paper introduces the basic fracture mechanics parameters of advanced building material - glass fibres reinforced cement based composite and its fracture and fatigue behaviour is investigated. To this aim three-point ...

The modified compact tension test (MCT) might become in the future a stable test configuration for the evaluation of fracture-mechanics parameters or also for description of fatigue behavior of composites materials such ...

For wedge splitting test specimens, the stress and displacement fields both in the vicinity and also in large distance from the crack tip are investigated by means of numerical methods. Several variants of boundary conditions ...

Táto práca sa zaoberá numerickou podporou stanovenia lomovo mechanických parametrov pri modifikovanej CT skúške. Táto skúška sa javí ako vhodná alternatíva klasickej CT skúšky pre únavové testovanie kvazikrehkých materiálov. ...

In the case of quasi-brittle material, there is a zone of non-linear behaving material, near the crack tip. A major part of this zone forms a so-called fracture process zone (FPZ), where mechanisms of material toughening ...

V případě odhadu kritického zatížení vrubů složených ze dvou materiálů se v rámci zobecnění lineární elastické lomové mechaniky vychází z předpokladu převažujícího normálového módu zatěžování. Z toho se vychází i při ...
