Hooke’s Law for shear stress is a fundamental principle in the field of strength of materials, stating that the shear stress () in a material is directly proportional to the shear strain () experienced by the material, as long as the material remains within its elastic limit. Mathematically, Hooke’s Law for shear stress can be expressed as:
Where:
- is the shear stress (in pascals, Pa)
- is the shear modulus or modulus of rigidity (in pascals, Pa)
- is the shear strain (unitless)
