For an elastic body with a single degree of freedom (DOF) (for example, stretching or compression of a rod), the stiffness is defined as $${\displaystyle F}$$ is the force on the … Ver más Stiffness is the extent to which an object resists deformation in response to an applied force. The complementary concept is flexibility or pliability: the more flexible an object is, the less stiff it is. Ver más The inverse of stiffness is flexibility or compliance, typically measured in units of metres per newton. In rheology, it may be defined as the ratio of strain to stress, and so take the units of reciprocal stress, for example, 1/Pa.
