“…According to expressions (15) and (16), the coefficient does not enter the formula for the connection between forces˜(˜). This fact means that, by analyzing such dependences for various values of the parameter , one can trace the influence of the latter on the ratio between the critical values of force components.…”

The influence of a tangential displacement on the strength of the adhesive contacts between gradient materials with different gradings of their properties has been studied. Variants with a controlled force (fixed load) and a controlled displacement (fixed grips) are considered. A relationship between the normal and tangential critical force components at which the contact is destroyed is obtained. It is valid within the whole interval of the gradient parameters, where the detachment criterium is obeyed. The optimal parameters at which the adhesive contact strength is maximum are determined. A case of detachment under the action of only the tangential force, i.e. when the normal force equals zero, is analyzed separately.

We consider an actuator whose driving bodies are made of Power-Law graded materials. The directional motion is generated by an asymmetric mechanism producing simultaneously vertical and horizontal oscillations of the indenter. The dynamic contact of gradient materials is described and the equation of motion for the drive is written down and analyzed. It is shown that the exponent of the elastic inhomogeneity significantly affects the average velocity of motion of the cargo, which can be dragged by the drive.

A one-dimensional wear contact problem for a functionally-graded elastic coating attached to a rigid base is considered under the condition of a constant pre-strain with the effect of the coating thickness evolution taken into account. It is assumed that the wear coefficient is inversely proportional to the material stiffness at the bearing surface. The presented analysis is primarily given in the dimensionless form in order to illustrate qualitative features of the model behavior. It is shown that the wearing-out period essentially depends on the wear coefficient variation with depth. It is found that the optimal design of FGM bearings is constrained by the maximum of the grading gradient of material properties.
