Multilevel models of endurance limits prediction for heterogeneous materials under complex stress state
The coupled boundary-value problem of composite micromechanics is presented and formulated. The problem is closed by kinetic equations, which describe possible scenarios of damage evolution.

| description | The coupled boundary-value problem of composite micromechanics is presented and formulated. The problem is closed by kinetic equations, which describe possible scenarios of damage evolution. The results of biaxial (i.e buckling and torsion) high-cycle fatigue tests with powder-iron samples and quasistatic tests under uniaxial tension and torsion are presented at the paper. Based on the dates of quasistatic tests theoretical method for cyclical durability prediction is developed, and theoretical Wöhlers curves are plotted for powder-iron. The comparison of mathematical simulation results and the dates of high-cycle fatigue tests is carried out. |
