The deformation module E, as the main physicomechanical characteristic of concrete, depends on both the age and composition of the concrete as well as the existing tensions. The tension and deformation relation is expressed by the deformation module. The dependence of the analytical function enables to find the voltage function formula. The non-linearity parameters included in the formula are determined by laboratory experiments.The relation between the strains and stresses for concretes as viscous elastic-plastic ageing environment is obtained
