elastic ratio

The part influencing area of prestressing force is related to such factors as concretes elastic ratio, beams sectional dimension and so on.

It is shown that Although the deformation curve under the pressure of axis is well consistent between micro-concrete and normal-concrete, the elastic ratio and strength are different.

This paper tries to introduce two suppositional variables which are named fictitious output and fictitious capital input in discussion for seeking a new method of measuring elastic ratio.
