Abstract: [cze] [eng]
Je ukázáno, jak lze prizmatem principu maximální rychlosti disipace energie, jako určité varianty 2. termodynamického zákona, korigovat Griffithovu koncepci lomové nestability. Praktické užití navrhovaného přístupu ukázalo na potřebu konstitutivních rovnic, respektujících skutečné mechanismy, vedoucí k lomu. Fracture theory based on thermodynamical laws, namely on the principle of the maximal dissipated energy rate is described. Application of this approach and comparison its results with classical FM criteria for prediction of critical loading is presented in framework of experiment on aluminium alloy specimens.
Keywords: nonlinear fracture mechanics, principle of maximum energy dissipation rate.
