Interests: My research is generally concerned with the investigation of fundamental industrial problems related to the processing, microstructure, and behavior of materials, ranging from metals to (nano-)composites for advanced structural and biomedical applications. My research focuses on scalable materials processing, including additive manufacturing and powder metallurgy, mechanical behavior at multiple length scales, bulk nanostructured alloys and composites, engineering biomaterials, and surface engineering.
Special Issue Information
Dear Colleagues,
Additive manufacturing (AM) has gained a lot of attention from both industry and academia. The combination of unique materials and incremental manufacturing in this technology provides opportunities for three-dimensionally structured parts with complex configurations and unique microstructures. However, while AM materials are emerging, their use is limited by the reliability of their mechanical properties, especially due to the fatigue behavior, due to the inherent process-induced imperfections (e.g., microporosity, high residual stresses, and large surface roughness). Indeed, a fairly high scatter in the fatigue strength of AM parts is commonly observed, which is attributed to the defects-induced stress concentration factors, which promote crack initiation at various locations. All of these necessitate further research in this area in order to increase the practicality of adopting AM in high-tech industrial applications.
Several important questions relating to the fatigue behavior of AM remain unexplored, notably the influence of building orientation and processing parameter, heat treatment, microstructural features for process-induced effects and the corresponding influence on quasistatic and fatigue properties, as well as understanding the damage and fracture mechanisms during cyclic loading.
In this Special Issue, we seek to provide a wide set of articles on current state-of-the-art research in fatigue behavior of additively-manufactured parts covering various materials systems that include metals and alloys, nanostructures, functionally gradient materials, porous materials, amorphous materials, shape memory alloys, high-entropy alloys, particle-reinforced metal/polymer matrix composites, and 3D tissues comprising multiple cell types. We welcome reviews and articles on the material design and process optimization, new assessment procedures and techniques, simulation methods, and experimental characterizations by integrating processing-microstructure-property relationships.
