  "id": "MLC-T-CHM-003495",
  "term": "Dynamic mechanical analysis",
  "field": "Chemistry",
  "definition": "A thermal analysis technique that measures the viscoelastic properties of materials as a function of temperature, time, or frequency. A sinusoidal stress is applied to a sample, and the resulting strain is measured, allowing determination of storage modulus, loss modulus, and damping factor. This technique is widely used for characterizing polymers and composites.",
