Mechanical stiffness
WebPurpose: To manufacture and test 3D printed novel design titanium spine rods with lower flexural modulus and stiffness compared to standard solid titanium rods for use in metastatic spine tumour surgery (MSTS) and osteoporosis. Methods: Novel design titanium spine rods were designed and 3D printed. Three-point bending test was performed to … The stiffness, $${\displaystyle k,}$$ 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 $${\displaystyle F}$$ is the force on the … See more 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. See more 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. See more The stiffness of a structure is of principal importance in many engineering applications, so the modulus of elasticity is often one of the … See more • Bending stiffness • Compliant mechanism – Mechanism which transmits force through elastic body deformation See more
