Forced sinusoidal oscillation

  "id": "MLC-T-CHM-004592",
  "term": "Forced sinusoidal oscillation",
  "field": "Chemistry",
  "definition": "A type of mechanical deformation applied to a material where a sinusoidal stress or strain is imposed, causing the material to oscillate at a specific frequency. In polymer rheology, this technique is used to probe the viscoelastic properties of polymers. The response of the material, including its storage and loss moduli, is measured as a function of frequency and temperature.",
