Stress may refer to:


  • Stress (mechanics), the average amount of force exerted per unit area. It is the internal resistance a material offers to being deformed and is measured in terms of the applied load. The effects of mechanical stress on a polymer can be measured using dynamic mechanical analysis.
  • Compressive stress, the stress applied to materials resulting in their compaction. It is the ability of a material to resist being crushed.
  • Tensile stress (also referred to as tension) is the stress state leading to expansion.
  • Yield stress, the stress at which a material begins to deform plastically.


  • Stress (biology), physiological or psychological stress; some types include:
    • Chronic stress, persistent stress which can lead to illness and mental disorder
    • Eustress, positive stress that can lead to improved long-term functioning
    • Workplace stress, stress caused by employment.


  • Compression (geology), the set of stresses directed toward the center of a rock mass
  • Shear (geology), the response of a rock to deformation usually by compressive stress and forms particular textures
  • Tension (geology), occurs when a rock is pulled apart in two opposite directions
