摘要
We develop a continuum mechanics theory of small deformations of isotropic composites made of elastic networks with significantly different mechanical properties such as hard and soft components. We show that those composites exhibit spatially non-local elasticity due to energetic coupling between the constituent networks. For realistic finite-size materials, this elastic property leads to a size-dependent Young's modulus. The size-dependent elasticity is generic and can be observed in a variety of composites consisting of largely different mechanical elements, which are ubiquitous in biological and synthetic soft materials.
