Thermography and tensile tests of steel samples. Study of material properties and internal friction effects

The thesis presents analysis of material properties and internal effects in steel samples, with varying temperatures. Uniaxial tensile tests were conducted in both room temperature and low temperatures, to generate graphical measures of the mechanical properties. The steel samples were monitored with thermography throughout the course of the tensile tests, to investigate the heat generation associated with internal effects. The analysis is limited to observations of change with temperature, and do not discuss the desirability. A numerical analysis with the finite element method was conducted for qualitatively comparison with the physical experiments
