The problem of determination of the service life of gearing is directly related to geometry of gears, multiaxial loadings, materials and appropriate models for prediction of the crack propagation.
Model for evaluation of service life Model of crack initiation The linear elastic fracture mechanics is inapplicable for describing properties of very short cracks, since elastic stress cannot accurately describe high deformation fields near the tip of small defects in high-strength materials.
Model of crack propagation Statistical analysis of experimental results shows that the material parameters in the equations of crack growth are random variables.
The basic aim of the measurements was to obtain a correlation between the micro crack length and stresses and/or how to conclude from the stress what happen in the material, when the crack occurs.

Special examples for identical materials were discussed in detail.
Bars are used to refer to the material constants associated with the upper half-space.
In order to carry out computations, we consider identical materials for simplicity in this section to give more explicit results of the problem.
Special examples for identical materials are computed and discussed in detail.
