Determination of the Temperature Influence on the Change of Young`s Modulus

Original language description

Materials commonly used in various branches of the engineering industries are very often tested under basic conditions. This is due not only to the frequent effort to determine e.g. mechanical properties of the tested material just under reference conditions but also to the assumption that some material characteristics remain constant over the entire range of material loading conditions. In this paper, the change of Young's modulus in dependence on temperature is studied. Stainless steel was selected as the test material. To determine the required Young's modulus of elasticity, a static tensile test was performed on a testing machine equipped with a split tube furnace which allowed the desired loading temperature to be adjusted (generally from RT to about 1,400 °C). The force channel was thus detected by means of a load cell (using bridge strain-gauge circuit) clamped in a testing machine. Specimen extension was simultaneously monitored using the external Mercury contact-less optical system, where the actual distance between two monitored points was measured. The entire system thus functioned as a "virtual" strain-gauge delivering the necessary specimen extension channel. From these measured characteristics, the corresponding Young`s modulus of elasticity was finally calculated as a function of temperature. The resulting temperature influence on the values of Young`s modulus change not only gives a better insight into the deformation behaviour of the tested material in the elastic deformation area, but can be also used in the numerical simulations of deformation processes.
