ABSTRACT
The increasing part of the stress-strain curve of concrete is a well-known exponential growing process, the first approximation of which is Hooke's law. It is followed, after the maximum, up to the point of inflection by an analogous exponential decreasing process. Finally, the curve ends after the point of inflection asymptotically with the best known exponential dying process. For steel, in the region of strain-hardening and the reduction area, we have similar results for the stress-strain relationship: In the region of strain-hardening, the function is an exponential growing process of the same mathematical form (with other parameters) as for concrete and also the following decreasing process in the reduction area is the same as for concrete.
