Abstract
At the designing stage it is necessary to take into account a plenty of factors influencing on constructions resistibility and solidity. One of them is various damages arising during a production process and also an exploitation. It causes a detailed study of concrete properties and reinforced-concrete constructions work under outer forces. Thus, one of the recently discovered concrete peculiarities is its susceptibility temporary breaches. Theses breaches are the most brittle structural to elements of material because of a specific capability to concentrate tensioning at its outfall. Their presence in the substance causes structural changes under the exploitation outer forces effects. This article describes J-integral method allowing to give an assessment of deformation energy release intensity during the temporary breach spread in bending constructions in a elastic-plasctic area. It gives the approach to calculate the energy flow to the force breach top developing like temporary.
