“By incorporating constituents of negative #stiffness [elasticity] in structures and composites, one can attain extremely high values of mechanical damping, stiffness considered as a viscoelastic modulus, of thermal expansion, or of other physical properties. Negative stiffness is of itself usually unstable but can be stabilized by incorporation in heterogeneous structures or composites.” #metamaterials #bibliography
on 02015-08-12Roderic Lakes’s #bibliography on composite #metamaterials that can have either negative or colossal thermal coefficients of expansion (#TCE) even if their components don’t. This is potentially useful for making nanometrically-precise #flexures without resorting to exotic materials like #Invar or maybe even metals.
