Engineering applications can involve complex tribological considerations other than the ranking and selection of materials. These can include such aspects as assessment of the significance of a variety of design parameters, determination of tolerances for these parameters, comparisons of designs, and life projections. Several of these are illustrated in terms of actual situations encountered by the author, along with the methods used to address these aspects in those cases. The typical needs of such applications of tribology are identified, and current approaches in wear modeling and wear testing are compared to these needs. Inadequacies are identified and suggestions as to how to address these are made. In addition, the differences between a material engineering and a more general design approach to engineering problems are identified, and the significance of these in terms of modeling and testing are discussed.
