Material Testing
Material testing Mechanical testing have been designed to test several weld properties.Few other material testing techniques are Charpy V-Notch Toughness: Notch toughness is the capacity that a material possesses to absorb energy in the presence of a flaw , such as a notch or crack. The material will likely exhibit a lower level of toughness. When a flaw is present in a material, loading induces a triaxial tension stres s state adjacent to the flaw. The material develops plastic strains as the yield stress is exceeded, near the crack tip. Notch-toughness is measured with a variety of specimens such as the Charpy V-notch impact specimen or the dynamic tear test specimen. As with regular impact testing the tests are often repeated numerous times with specimens tested at a different temperature. With these specimens and by varying the loading speed and the temperature, it is possible to generate curves such as those s...
