Our latest version of the dynamic mechanical Yerzley oscillograph, Model V that returns results within three seconds. It can report:

  • phase angle
  • tan delta
  • log decrement and loss angle
  • point modulus
  • dynamic modulus
  • impact energy

Our legacy machine that predicts the mechanical properties of rubber, plastics and other polymers in a small range of deformations. ASTM D 945-16 test method calls using this machine to characterize mechanical properties:

  • initial creep
  • initial set
  • impact energy
  • frequency
  • effective dynamic modulus
  • point modulus
  • Yerzley Resilience
  • Yerzley hysteresis
  • tangent of Delta
