Аннотация: The analysis of the effect of elastic interaction between asperities of 2D regular rough surface on the peak pressure is performed on the basis of contact problems for sinusoidal geometry with single, double and infinite contact zones. The new asymptotic expression for pressure distribution in the contact of two sinusoidal asperities with an elastic half-plane was obtained using Gladwell’s approach. The results of the analysis show, that the effect of elastic interaction leads to increase of maximum pressure value and reduction of the contact zone size. Despite significant discrepancy in pressure distributions for different types of contact (single, double and periodic), elastic interaction produces only slight effect on the peak pressure dependence at light and moderate loads.
