The role of granular matter in additive manufacturing
Additive manufacturing, particularly in granular systems, has revolutionized industries such as aerospace, medical engineering, and automotive manufacturing by enabling complex, customized designs. A critical aspect of additive manufacturing is powder handling, which involves challenges related to deposition, packing density, and safety. Numerical simulations, including the discrete element method and smoothed particle hydrodynamics, play an essential role in optimizing these processes. Inspired by the DEM9 conference, where several authors were invited to contribute, this editorial highlights ongoing granular research on additive manufacturing. Previously not extensively covered in Granular Matter, this topical collection showcases novel work to establish additive manufacturing more prominently within the journal. Through contributions on powder spreading, material structure, and innovative computational models, this issue enhances the understanding of additive manufacturing processes and their industrial applications.
期刊介绍：
Although many phenomena observed in granular materials are still not yet fully understood, important contributions have been made to further our understanding using modern tools from statistical mechanics, micro-mechanics, and computational science.
These modern tools apply to disordered systems, phase transitions, instabilities or intermittent behavior and the performance of discrete particle simulations.
>> Until now, however, many of these results were only to be found scattered throughout the literature. Physicists are often unaware of the theories and results published by engineers or other fields - and vice versa.
The journal Granular Matter thus serves as an interdisciplinary platform of communication among researchers of various disciplines who are involved in the basic research on granular media. It helps to establish a common language and gather articles under one single roof that up to now have been spread over many journals in a variety of fields. Notwithstanding, highly applied or technical work is beyond the scope of this journal.
