Computational Mechanics Model to Evaluate the Structural Maintenance of Catenated Hydrogen‐Bonded Organic Frameworks

Small, EarlyView.
This study presents a computational framework treating crystalline HOFs as adaptive atomic‐scale interfaces. Catenated HOFs preserve lattice stability under load while enabling auxetic deformation and reversible nonlinearity. The results provide direct evidence that supramolecular interactions govern macroscopic resilience and structural adaptability ...

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Dynamic Covalent Polymeric Foams: En Route to a Sustainable Lightness

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
Dynamic covalent polymer foams (DCPFs) combine lightweight cellular structures with adaptive polymer networks, enabling self‐healing, reprocessability, and recyclability. By integrating reversible covalent bonds into foam architectures, these materials open new pathways toward sustainable porous polymers within a circular materials economy.

Aircraft Wing Morphing Using Auxetic Structures

International Journal of Innovative Science and Research Technology (IJISRT)
Cellular materials exhibit two key properties: structures and mechanisms. This allows for the design of structures using cellular materials while effectively controlling both stiffness and flexibility, based on the connectivity of the struts. This study aims to explore the in-plane flexible properties of cellular materials dominated by bending under ...
