Material property of a solid body measuring as
proportionality coefficient between tensile stress \sigma (force per unit area) and axial strain \epsilon(proportional deformation) in the linear elastic region of a material:
| (1) | E' = \frac{E}{1-\nu^2} |
where
It has a meaning of proportionality coefficient between plane stress and plane strain under plane stress conditions (when stress vector is zero across a particular plane).
