Extensometry \u2013 Strain and displacement measurement\"video<\/h2>\n

What is extensometry?<\/span>Extensometry enables the measurement of localized strain or displacement on a material subjected to tensile, compression, flexural or peel testing.
3R offers a wide range of mechanical, automatic or video extensometers, suited to each type of test and material.<\/p>\n

Why use an extensometer?<\/h3>\n

An extensometer enables:<\/p>\n

    \n
  • Precise monitoring of strain over a targeted zone<\/strong>,<\/li>\n
  • Controlling a test at strain<\/strong> or opening rate (e.g. crack),<\/li>\n
  • Objectively comparing<\/strong> samples,<\/li>\n
  • Capturing the actual behavior<\/strong> of the material, independent of machine compliance,<\/li>\n
  • Working on fragile specimens<\/strong>, flexible materials, or over large displacement ranges<\/li>\n<\/ul>\n

    Types of tests achievable with extensometry<\/h3>\n
      \n
    • Tensile testing on metals<\/strong> (modulus measurement, elongation at break)<\/li>\n
    • Tensile testing on polymers<\/strong>, composites<\/strong> (elastic and plastic behavior)<\/li>\n
    • Compression<\/strong> (instability, transverse strain)<\/li>\n
    • Flexural testing<\/strong> 3 and 4 point (central or average deflection)<\/li>\n
    • Behavior at temperature<\/strong> (hot metals, polymers)<\/li>\n
    • Measurement on long structures<\/strong> or rebar (elongation over large gauge length)<\/li>\n<\/ul>\n
