Effective elastic properties of composites of ellipsoids (I). Nearly spherical inclusions

Wei, Gaoyuan; Edwards, S.F. - In: Physica A: Statistical Mechanics and its Applications 264 (1999) 3, pp. 388-403

Poisson ratio, it is found that auxeticity windows for both inclusion volume or area fraction and the ratio of Young's modulus … in the case of rigid auxetic inclusions randomly embedded in an incompressible matrix. For a matrix having a non-negative …

Auxeticity windows for composites

Wei, Gaoyuan; Edwards, S.F. - In: Physica A: Statistical Mechanics and its Applications 258 (1998) 1, pp. 5-10

Materials with negative Poisson ratios are known to have high shear rigidities – a useful property for many types of structural and functional materials. To improve upon relatively low Young’s modulus of existing auxetics, one may consider embedding such components in an elastic material...
