Change of Young’s Module on Steel Specimens with Corrosion by Experiment

Antonio Shopov and Borislav Bonev
Abstract—Nowadays, corrosion on steel structures is a common occurrence. The reasons that lead to the appearance of corrosion in structures are well-know as well as its negative impact of them. The possibility of re-use corroded steel elements into the construction should be ascertained and how this would affect the calculation and the design of the structure. We conducted an experiment to determine how the modulus of elasticity of corroded steel specimens was changed. We applied an electrochemical accelerated corrosion method to our S355JR steel specimens. After that we tensile- tested them, we took the values from the stress-strain diagrams and calculated the module change. We also applied the stochastic way of processing of the results. We have reached a conclusion that corrosion indicates a serious impact on the modulus of elasticity, even leading to a change of material, i.e. from ductile material, it subsequently becomes a brittle material, which circumstance should be taken into account in the re-use of corroded elements in their calculation and design.

Index Terms—Young’s module, corrosion, accelerated corrosion, steel specimen.
