    Analiza rozwoju uszkodzenia i trwałych odkształceń próbek dolomitu poddanych quasistatycznym jednoosiowym obciążeniom
    (Wydawnictwa AGH, 2010) Cieślik, Jerzy
    This paper presents results of uniaxial quasistatic compression tests of dolomite samples. The main topic addressed was the analysis of rock samples failure in macro scale and observation of some micro mechanical failure processes effects. The micro mechanical processes (fracture or rock and grain slips) was analyzed by irreversible strain observation and calculated as different energy dissipation during loading and unloading of rock samples. A relationship between these micro mechanical failure processes and axial and lateral irreversible strain was shown in various strain rate loading conditions. All the tests were performed for a range of pre failure stress strain characteristics only.
