The aim of this paper is to investigate the beginnings of crack propagation from sharp V-notches. Stress distribution around the tip of a V-notch is described on the basi [...]

The stability criteria of V-notched bodies under combination of loading modes I and II are suggested and compared in the article. Methodology of stability criterion sugge [...]

A two-parameter fracture mechanics method is applied to small cracks near a stress concentrator. The small crack in the present contribution is considered as crack influe [...]

In case of two-parameter linear fracture mechanics a study of inhomogeneity influence on behaviour of short cracks is performed. The values of stress intensity factor (KI [...]

Under the assumptions of linear elastic fracture mechanics the behaviour of cracks and general singular stress concentrators is studied and compared. The stress distribu [...]

Concrete is represented as a two-phase material in this paper. Behaviour of a crack with its tip on the interface between two different materials - hardened cement paste [...]

Abstrakt: Existence of the interface between regions with different elastic properties have a pronounced influence on the behaviour of cracks The aim of the present contr [...]

Abstrakt: A stability criterion based on generalized strain energy density factor for a crack terminating at the bi-material inteiface is suggested. The strain energy den [...]

Abstrakt: V příspěvku jsou prezentovány výsledky lineární elastické lomové mechaniky V-vrubů. Jsou formulovány obecné podmínky stability V-vrubů a diskutov� [...]

Abstrakt: Při stanovováni lomových charakteristik betonu a dalších cementových kompozitů je využívána zkouška tříbodovým ohybem trámců se zářezem. Efekt [...]
