PHYSICAL MODEL OF A 6-CONSTANT ANISOTROPIC ELASTIC MATERIAL

Abstract

The physical model of a multi-constant elastic material, with consideration of couple-stresses, is studied critically to determine whether it more reasonably represents a 3-constant isotropic material or a 6-constant centro-symmetric cubic crystalline material. A description of a critical shear experiment on the model is presented along with experimental results. A parameter alpha which is definitively related to the question is defined and its value determined on the basis of statical deformation experiments. The conclusion is that the model behaves as a cubic crystal showing couplestress effects.
