Item type:Article, Access status: Open Access , Zmiany energetyczne związane z rozwojem uszkodzenia i dyssypacją plastyczną w teście jednoosiowego i trójosiowego ściskania próbek piaskowca(Wydawnictwa AGH, 2011) Cieślik, JerzyResults of laboratory investigations focusing on energy changes with damage and plastic dissipation process under a uniaxial and triaxial compression tests of sandstone samples has been presented in this paper. It was assumed, that fracture propagation and plastic dissipation caused by compression of rock samples follows by coupled damage and plasticity mechanical model. Based on this model and the principle of conservation of energy, damage and the plastic dissipation energies was determined separately.
