Physical experiments dealing with the problem of lateral pressure of granular materials proceed some years using medium-size models of the ideal non-cohesive granular mas [...]

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

This article deal with problems of cracks in bodies with bimaterial interface. The stress and displacement near the front of crack located at the interface between two or [...]

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 [...]

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 [...]

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 [...]

Abstrakt: Relations between crack opening displacement (CTOD) and other fracture mechanics parameters are of a great importance in fracture mechanics. The basic aim of t [...]
