Material selection strategies for environmental-based fatigue design

Abstract

Environmental imperatives require that the environmental consequence of material selection be minimized. This can be achieved by assessing the relative environmental impact of the candidate materials. However, limitations of traditional material selection tools may result in non-optimal outcomes for fatigue-limited applications. The novel material selection tools discussed in this paper seek to improve design decision-making through increased quantitative certainty. Fatigue-limited material selection procedures presented in the literature to evaluate the environmental impact for infinite-life design are not directly suited to finite-life design. In response to this deficiency, a novel design..
