Active Metamaterials with Tunable Shear Nonreciprocity and Nonlinear Dynamics
Advanced Science, Volume 13, Issue 28, 18 May 2026.Active gear‐based mechanical metamaterials enable simultaneous control of translational and torsional stiffnesses by 30–100×, break shear reciprocity under positive versus negative loads, broadly tune resonant frequencies, and offer programmable dynamic responses.

Nonlinear morphoelastic plates II: exodus to buckled states [PDF]
, 2010 Morphoelasticity is the theory of growing elastic materials. This theory is based on the multiple decomposition of the deformation gradient and provides a formulation of the deformation and stresses induced by growth.

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 ...

Bioinspired 3D‐Printed NiTi Metamaterials With Bivalve‐Like Crossed‐Lamellar Structures
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Metamaterials demonstrate unique mechanical properties and functional performance owing to their distinctive topological spatial structures. In this study, by mimicking the natural Saxidomus purpuratus shell, bioinspired crossed‐lamellar architectures with interlamellar apex angles ranging from 60° to 150° were designed and fabricated in NiTi ...

Global instabilities of pyramidal trusses
Trends in Computational and Applied MathematicsThis paper presents an exact analytical study of global instabilities in pyramidal trusses under large displacements. Using the stationarity of total potential energy and Green-Lagrange strain, non-linear equilibrium equations are derived for a 3-bar ...

Buckling Paradox And Anisotropic Plastic Plate Bifurcation [PDF]
Progress in Canadian Mechanical Engineering, 2018 Anisotropic elastic/plastic plate bifurcation is investigated. The pre-bifurcation loading consists of biaxial stresses along ξν axes parallel to the sides of a simply supported rectangular plate: ννξξσασ=,11α−≤≤. The ξν axes are at an angle βwith the xy principal axes of anisotropy.
