Programmable crack dynamics engineering enables flexible strain sensors with high linearity

FlexMat, EarlyView.
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.

Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

physica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...

On the Origins of Out‐of‐Plane Auxetic Response in Paper

physica status solidi (b), EarlyView.
Paper can be auxetic! Paper can exhibit a range of out‐of‐plane Poisson's ratio (PR) values. Examining handsheets made from hardwood (HW) and softwood (SW) fibers, of a variety of weights (1, 3, or 5 g) and refining degrees (none, R, or R+), showed that the sign and magnitude of PR can be finely controlled by modifying network parameters.
