Shear

  "id": "MLC-T-OAG-003356",
  "term": "Shear",
  "field": "Oil and gas",
  "definition": "A type of stress that causes parts of a body to slide relative to each other in a direction parallel to their plane of contact. In geophysics, this deformation is associated with shear waves, or S-waves, which involve particle motion perpendicular to the wave's direction of travel. Unlike compressional stress, shear stress changes the shape of a material without changing its volume, and its magnitude is measured in pascals.",
