R. Zheng, B. Yi, J. Liu, L. Liu, X. Peng and G. H. Yoon. Engineering Structures 345, 121552 (2025). Mechanical metamaterials have garnered significant attention due to their unique properties, such as low stiffness-to-weight ratio and auxetic behavior. However, the fabrication of large-scale mechanical metamaterials remains challenging due to the limitations of curre...

M. Shin and G. H. Yoon. Structural and Multidisciplinary Optimization 68:190 (2025) This research employs a topology optimization based on deep reinforcement learning (DRL) technique to design structures for noise reduction. Reinforcement learning (RL) is a type of machine learning in which an agent gradually learns to find the optimized solution through various experie...

H. M. Lee, M. J. Park, and G. H. Yoon. Powder Technology 468, 121589 (2026). Granular beds subjected to vertical mechanical vibration become fluidized and exhibit convection patterns, yet the influence of vibration energy input on the convection rate remains underexplored. Here, we demonstrate that a unified energy parameter 𝜀, which encapsulates both velocity and a...

Y. D. Yoon and G. H. Yoon. Structural and Multidisciplinary Optimization 68, 86 (2025). This paper presents a novel approach to optimizing the design of structures for controlling particle behavior through the application of Bayesian optimization techniques. Particle behavior is highly sensitive to initial conditions, leading to uncertainty in predicting behavior. ...
