• Strain (chemistry)
  Strain (chemistry)
  In chemistry, a molecule experiences strain when its chemical structure undergoes some stress which raises its internal energy in comparison to a strain-free reference compound. The internal energy of a molecule consists of all the energy stored within it. A strained molecule has an additional...
  
  , a chemical stress of a molecule. The effects of strain on a compound can be measured using dynamic mechanical analysis
  Dynamic mechanical analysis
  Dynamic mechanical analysis is a technique used to study and characterize materials. It is most useful for studying the viscoelastic behavior of polymers. A sinusoidal stress is applied and the strain in the material is measured, allowing one to determine the complex modulus...
