The stiffness, of a body is a measure of the resistance offered by an elastic body to deformation. For an elastic body with a single degree of freedom (DOF) (for example, stretching or compression of a rod), the stiffness is defined as where, is the force on the body.

Stiffness is the resistance of an elastic body to deflection or deformation by an applied force - and can be expressed as. k = F / δ (1) where . k = stiffness (N/m, lb/in) F = applied force (N, lb) δ = extension, deflection (m, in)
May 6, 2023 · Stiffness is the rigidness of any object or material. Objects with a high stiffness will resist changes in shape when being acted on by a physical force. For example, loose, wet clay has low stiffness, changing shape with just a few pounds of pressure. The stiffness of aluminum is considerably stiffer than wet clay.
Jan 19, 2018 · The main difference between strength and stiffness is that strength is the ability of an object to withstand stress without breaking whereas stiffness is the ability of an object to resist deformation when a stress is applied.
