Отрывок: We compared our observations with results of classical linear fracture mechanics, given in Tables above. For all cases of mixity parameter studied in molecular dynamics calculations our measurements of crack propagation directions are close to the theoretical results obtained for multi- parameter fracture criteria (column 2 of Tables 1-4). From our simulations we can get crack propagation directions and crack angles. Calculations were run for t...

dc.description.abstract | Atomistic simulations of the central crack growth process in a plane medium using Large-scale Molecular Massively Parallel Simulator (LAMMPS), a classical molecular dynamics code, are performed. The inter-atomic potential used in this investigation is Embedded Atom Method (EAM) potential. The specimens with initial central crack were subjected to Mixed-Mode loadings. The simulation cell contains 400000 atoms. The crack propagation direction angles under different values of the mixity parameter in a wide range of values from pure tensile loading to pure shear loading in a wide diapason of temperatures (from 0.1 К to 800 К) are obtained and analyzed. It is shown that the crack propagation direction angles obtained by molecular dynamics method coincide with the crack propagation direction angles given by the multi-parameter fracture criteria based on the strain energy density and the multi-parameter description of the crack-tip fields. | ru |
