Purpose This paper aims to present a proposal for evaluating the coefficient of friction (COF), under a reciprocating test that considers the energy dissipated by the friction force. In addition, this new parameter is compared to average COF, which i

The checkerboard phenomenon is a numerical problem that can occur in bone remodeling simulations. This phenomenon degrades the quality of the results and emphasizes a strong mesh dependency. The node-based approach is a well-used method for solving t

A constant challenge in the automotive industry is to find ways to reduce the friction. Reductions in the weight of components can play this role, but for using smaller thickness in the engine blocks more resistant materials should be employed. The p

Surface roughness parameters of mechanical components are sensitive to systematic errors, which can cause significant deviations in their values. These parameters are commonly used for manufacture controlling or even for tribological applications, su

The superficial characteristics of honed surfaces are relevant for the tribological performance of cylinders of internal combustion engines (MCI). Recent studies found a correlation between the occurrence of the phenomenon called folded metal and the
