- Stress and strain are fundamental concepts in engineering and strength of materials. Here are some key points about them:
- Stress is the force applied per unit area, while strain is the deformation or displacement per unit length1.
- They are directly proportional up to an elastic limit according to Hooke’s law2.
- Stress expresses internal forces between particles, while strain measures relative deformation3.
- Stress is typically measured in Pascals (Pa) or Megapascals (MPa)1.
- Strain is dimensionless1.

Stress–strain curve - Wikipedia
In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain. It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing). These curves reveal many of the properties of a material, such as the Young's modulus, the yield strength and the
