    Ocena stanu technicznego eksploatowanych gazociągów stalowych
    (2007) Wilk, Stanisław; Galas, Marek; Traple, Jacek
    The evaluation of technical state of steel gas pipelines after a long time of exploitation are presented in the paper. The evaluation methodics was exemplified. The field and laboratory results of evaluation of technical state of steel pipelines after a long exploitation time were quoted in view of the corrosion processes as well as strength tests on the pipeline material.

    Test punktowy, test brazylijski i test na jednoosiowe ściskanie - badania porównawcze
    (Wydawnictwa AGH, 2008) Piątek, Patrycja
    The results of the point load test, Brazilian test and uniaxial compression test of cylindrical samples are presented in this paper. Sandstones of different grain size, coming from several collieries in the Upper Silesian Coal Basin, were selected for the studies. Based on the test results, values of the conversion factor that occurs in the linear relationship between the uniaxial compressive strength and point-load strength index and between the tensile strength and point-load strength index have been determined for the sandstones tested. When analysing the experimental results, particular attention was paid to the fracturing mode of rock samples under point load conditions.
