Designing Limited-Life Structures- Predicting Fatigue Life and Ductile Fracture of Additively Manufactured Materials
Abstract
This proposal presents a novel approach for predicting fatigue life and ductile fracture in additively manufactured materials with anisotropic properties. The rapid advancement of additive manufacturing (AM) has revolutionized the production of complex and high-performance parts across various industries, particularly in aerospace. However, integrating AM into structural systems presents substantial challenges such as achieving consistency in production scale, ensuring structural integrity. Existing methodologies often inadequately model the unique anisotropic properties inherent in AM materials, leading to gaps in predictive accuracy. Our research proposes to develop advanced predictive models that accurately simulate and predict the behavior of AM materials under diverse stress conditions. These models will be rigorously tested and validated through advanced simulations, aiming to significantly enhance the reliability and efficiency of limited life structures. The anticipated outcomes of this study are expected to make significant contributions to the fields of various engineering and materials sciences, ultimately improving the design and application of AM components.
