Kumar, Abhinav (author), Gupta, Ankit (author), Anupam, K. (author), Wagh, Vivek Pratap (author)In most of developing countries across the world, pavement design is still based on an empirical approach that may result in premature failure or overdesigned pavements. A shift from an empirical to a semi-mechanistic or mechanistic approach is the need of modern time. In this regard, computational tools such as finite element (FE) are being...journal article 2024

Pinskier, Josh (author), Wang, Xing (author), Liow, Lois (author), Xie, Yue (author), Kumar, Prabhat (author), Langelaar, Matthijs (author), Howard, David (author)Soft grippers are ideal for grasping delicate, deformable objects with complex geometries. Universal soft grippers have proven effective for grasping common objects, however complex objects or environments require bespoke gripper designs. Multi-material printing presents a vast design-space which, when coupled with an expressive computational...journal article 2024

Guo, Y. (author), Sharma, S. (author), Kumar, Siddhant (author)Smooth and curved microstructural topologies found in nature—from soap films to trabecular bone—have inspired several mimetic design spaces for architected metamaterials and bio-scaffolds. However, the design approaches so far are ad hoc, raising the challenge: how to systematically and efficiently inverse design such artificial...journal article 2024

Singh, Diwakar (author), Sharma, S. (author), Kumar, Rajeev (author), Chauhan, Vishal S. (author), Vaish, Rahul (author)Although conventional actuators like piezoelectric and electrostrictive are efficient, but they required hard wiring, which contaminates the control signal and adds to the weight of the structure. The current study presents a wireless control strategy using photostrictive actuators. Owing to the fortunate combination of photovoltaic effect...journal article 2023

van 't Sant, S. (author), Thakolkaran, P. (author), Martínez, Jonàs (author), Kumar, Siddhant (author)Advancements in machine learning have sparked significant interest in designing mechanical metamaterials, i.e., materials that derive their properties from their inherent microstructure rather than just their constituent material. We propose a data-driven exploration of the design space of growth-based cellular metamaterials based on star-shaped...journal article 2023

(author), Wagemaker, M. (author)Developing liquid electrolytes with higher kinetics and enhanced interphase stability is one of the key challenges for lithium batteries. However, the poor solubility of lithium salts in solvents sets constraints that compromises the electrolyte properties. Here, it is shown that introducing multiple salts to form a high-entropy solution,...journal article 2023

Zheng, Li (author), Karapiperis, Konstantinos (author), Kumar, Siddhant (author), Kochmann, Dennis M. (author)The rise of machine learning has fueled the discovery of new materials and, especially, metamaterials—truss lattices being their most prominent class. While their tailorable properties have been explored extensively, the design of truss-based metamaterials has remained highly limited and often heuristic, due to the vast, discrete design space...journal article 2023
