...Yifan Zhou; Wenlei Zhang; Jian Hu; Jingda Tang; Chenyu Jin; Zhigang Suo; Tongqing Lu Stiffness and fatigue threshold are important material parameters in load-carrying applications. However, it is impossible to achieve both high stiffness and high threshold for single-network elastomers and single...

...Hassan Bahaloo; Yaning Li Based on micropolar continuum theory, the closed-form stiffness tensor of auxetic chiral lattices with V-shaped wings and rotational joints were derived. Representative volume element (RVE) of the chiral lattice was decomposed into V-shape wings with fourfold symmetry...
