Title of the articleTo the effect of «strain hardening» concrete under tensile mechanical load
Abstract.Problem statement. In this work tasked to explain the mechanism of the concrete «strain hardening» which observed in experiments under tensile mechanical stress – from start of loading to the moment preceding appearance of the visible macrocrack. Results. To do this, the analysis of the analogies in metals and alloys studied by theoretical and experimental material. In the end, based on the model of Conrad the obtained inequality to estimate the tangential stresses corresponding to the end of «strain hardening» in cement stone (concrete). Conclusions. The significance of the results for the construction industry is the application of dislocation theory to the explanation of the process of «strain hardening».
Keywords.work hardening, concrete, cement stone microstructure, discontinuity, dislocation.
