Conclusions

1. With the aid of averaging integrals, it is possible to arrive at various approximations for the elastic parameters of a material with microdefects in the form of plane cracks.

2. These approximations differ appreciably in the case of high crack concentrations, with the use of a self-consistent field in both the Reiss model and the Voigt model yielding different results.

3. In the absence of information about the microdefect structure in a material, the defectiveness parameters must be determined from a macrotest under conditions of a plane state of stress. The expressions derived on this basis will then yield predictions as to changes in the mechanical properties under other conditions of stress and loading.
