A mathematical model describing the contact interaction of a semi-infinite medium with a microstructure and a rigid flat punch is considered. The contact tangents and normal stresses are related by the Coulomb-Amonton friction law. The microstructure of a semi-infinite medium is described by equations of the heterogeneous two-phase Bio medium. The boundary problem describing the present problem is reduced to the integral equation of the first kind with a logarithmic kernel. The solution of the integral equation is based on the iterative algorithm. Formulas describing the stress-strain state in the contact region are obtained. The influence of the microstructure of a semi-infinite medium and the speed of the punch movement on the stress-strain state in the contact region is studied.
