Abstract
The authors analyze the structure of the elasticity tensors and compliance coefficients in a special linearly elastic and transversely isotropic material with paradox behavior. The intrinsic moduli and states are found for the elasticity tensors if this material. The extreme values of Young’s modulus, shear modulus and Poisson’s ratio are determined. The characteristics of the nearest tensor of elasticity moduli are obtained.
