MEASUREMENT IN TENSILE TEST OF TRUE STRESS-STRAIN CURVES FOR LOW-CARBON STEEL1)

  • In order to measure the true stress-strain curve of low carbon steel, an experimental teaching system based on a single camera three-dimensional digital image correlation system is developed. The system can be used to measure the three-dimensional surface morphology and the surface strain in the tensile test of a low carbon steel bar, and obtain its true stress-strain curve. This experiment helps the students to understand the mechanical properties of plastic metal materials and cultivate their interest in the scientific research.
