This work provides some ecological criteria for fatigue designers so that they can quantitatively consider the ecological impact as a factor during the process of design. In particular, during the selection of materials for fatigue applications, two kinds of applications have been examined. The first one is related to components under cyclic loading with no energy consumption during their use, as a pipe under variable pressure. In this case, the highest impact takes place during the material production phase. The second application refers to components used in means of transport, as planes or cars components. For them, the highest environmental impact occurs during the use phase, through fuel consumption. For both applications, a parameter is provided, named Ecological‐Fatigue Factor , that combines both the ecological impact and the fatigue endurance of the materials. For the two applications, a ranking of materials based on the Ecological‐Fatigue Factor is given. Great differences can be found between the two rankings.
