Behavior of Elastoplastic Auxetic Microstructural Arrays
A continuum-based micromechanical model is employed for the prediction of the elasto-plastic behavior of periodic microstructural arrays that can generate negative values of Poisson's ratios. The combined effects of the negative Poisson's ratio generated by the array microstructure and the elastoplastic behavior of the constituents are studied. A design methodology for the determination of the ...
متن کاملElasto-static micropolar behavior of a chiral auxetic lattice
Auxetic materials expand when stretched, and shrink when compressed. This is the result of a negative Poisson’s ratio n. Isotropic configurations with n 1 have been designed and are expected to provide increased shear stiffness G. This assumes that Young’s modulus and n can be engineered independently. In this article, a micropolarcontinuum model is employed to describe the behavior of a repres...
متن کاملDynamic behavior and damping capacity of auxetic foam pads
A novel set of auxetic (negative Poisson's ratio) open cell polyurethane foam has been developed and tested under dynamic loading conditions to assess the viscoelastic response under white noise random excitation and compressive cycling. Foam pads normalized to standard ISO 13753 have been tested at room temperature and frequency bandwidth 10-500 Hz to assess transmissibility characteristics fo...
متن کاملSoft Actuation of Structured Cylinders through Auxetic Behavior
There has been a recent upsurge in the study of auxetic, or negative Poisson’s ratio, materials that derive functionality from mechanical instabilities of the underlying structure. One of the simplest auxetic designs comprises an elastomeric slab patterned with an array of voids. Under uniaxial compression, the slender ligaments contiguous to the voids buckle cooperatively, resulting in the shr...
متن کاملAuxetic Black Phosphorus: A 2D Material with Negative Poisson's Ratio.
The Poisson's ratio of a material characterizes its response to uniaxial strain. Materials normally possess a positive Poisson's ratio - they contract laterally when stretched, and expand laterally when compressed. A negative Poisson's ratio is theoretically permissible but has not, with few exceptions of man-made bulk structures, been experimentally observed in any natural materials. Here, we ...
