The strength of the forces that cause deformation is expressed by stress. The extent of deformation under stress is expressed by strain, which is dimensionless. Tensile (or compressive) stress, which causes elongation (or shortening) of the object or medium and is due to external forces acting along only one direction perpendicular to the cross-section.

Compressibility of an object or medium is the reciprocal of its bulk modulus, the elastic modulus in this case. Shear strain is the deformation of an object or medium under shear stress. Shear stress is caused by forces acting along the object’s two parallel surfaces.

For small deformations, two important characteristics are observed. First, the object returns to its original shape when the force is removed—that is, the deformation is elastic for small deformations. Second, the size of the deformation is proportional to the force—that is, for small deformations, Hooke’s law is obeyed.
