Elastic and viscoelastic behavior of chiral materials. (English) Zbl 1049.74012

From the summary: We consider effects of chirality in elastic materials described by a generalized continuum representation, specifically Cosserat elasticity. Analysis of several configurations discloses a chiral material to generate reaction moments when compressed as a slab. A chiral plate bent to hyperbolic shape is predicted to exhibit size effects from the Cosserat characteristic length, and a shear force from the chirality. This analysis can be used for the interpretation of experiments on compliant chiral materials, in particular the evaluation of elastic constants. Viscoelastic chiral solids are examined in the context of the correspondence principle.
