Tensile Strength Testing
Tensile strength testing is conducted using a meticulously calibrated universal testing machine with a force rating of up to 1,000 kN. This versatile test can be applied to both rebar and prestressing wire or strands, providing direct measurements of yield strength and tensile strength. For a comprehensive analysis that includes the elastic modulus, the installation of a strain gauge is necessary to ensure the precise determination of this parameter. When testing specimens from steel or concrete structures, careful planning is essential, as obtaining a steel specimen involves cutting it into a round or flat bar form. This cutting process, though inevitable, can potentially impact the structural integrity of the elements, necessitating strategic choices for cutting locations to minimize any adverse effects on the strength of the structures.
