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, denoted by the letter (k), is a measure of the resistance of an object to deformation in response to an applied load. In other words, stiffness is the ability of a material or a structure to resist bending, twisting, or stretching.

Stiffness definition: the state or condition of being rigid or firm. See examples of STIFFNESS used in a sentence.
Defining Stiffness: Stiffness Meaning In the context of solid mechanics, stiffness is a material property indicating how much it deforms under a magnitude of force. This is represented mathematically by the equation: \[ \text{Stiffness} (K) = \frac{\text{Force (F)}}{\text{Displacement (d)}} \]
