Chirality affects microcritical, not macrocritical, stability
—
in MechanicsAnalysis of periodic lattice metamaterials with rigid joints shows chirality affects microscale stability but not macroscale stability, enabling tailored critical mode activation.
Foam filling improved the performance of SLS polymer lattices
—
in EngineeringStudy evaluates SLS polymer lattice architectures with and without polyurethane foam filling, revealing foam integration increases stiffness 40-fold and strength nearly 100% while improving energy.
Oyster shell powder produced a magnesium foam with homogeneous pores
—
in MetallurgyClosed-cell magnesium foam produced with oyster shell powder as blowing agent contains only seawater-extractable components, enabling harmless marine dissolution.
Bio-inspired Voronoi tubes improved energy absorption
—
in EngineeringBio-inspired Voronoi tubular structures replicate luffa sponge architecture for enhanced energy absorption. Parametric design optimization increases specific energy absorption by up to 78%.
