It presents the results obtained from the analysis when the isosceles triangle surface ridge is shaved on the top i.e., when the contact surface ridge is isosceles truncated triangle. For the studied contact and surface ridges, the contact stiffness of the whole contact is obtained and compared for different degrees of the shaving of the surface ridge. The load-carrying capacities and contact stiffness of the direct contact between a single ridge and the smooth plane are studied for different surface ridge geometry parameter values. The load partitions in the contact are obtained for different degrees of the surface ridge shaving. The temperature rises on the ridge surface in the direct contact are computed for different degrees of the surface ridge shaving and for wide load ranges carried by the direct contact when the Poisson`s ratios, Young`s moduli of elasticity and compressive yielding strengths of the contact surfaces are, respectively taken as insensitive to the contact surface temperature rise. These obtained results are compared and the conclusions are drawn concerning the shaving of the contact surface ridge in the present mode of contact.
