Chentsov coefficients

Other anisotropic elasticity relations are used to define Chentsov coefficients that are to shearing stresses and shearing strains what Poisson s ratios are to normal stresses and normal strains. However, the Chentsov coefficients do not affect the in-plane behavior of laminaeS under plane stress because the coefficients are related to S45, S46, Equation (2.18). The Chentsov coefficients are defined as... 

Pij y = Chentsov coefficient that characterizes the shearing strain in the kl-plane due to shearing stress in the ij-plane, i.e.,... 

Note that the Chentsov coefficients are more effectively called the functional name of shear-shear coupling coefficients.
