### Stiffness

Term for the workability of a mix. The ease that a material requires to move it when hot.

### Stiffness

Stiffness is the rigidity of an object — the extent to which it 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. ==Calculations== where, In the International System of Units, stiffness is typically measured in newtons per metre. In I...

### stiffness

in a system in which friction and inertia are negligible, quotient of force at a point by the in-phase displacement at the point, caused by the force, during sinusoidal motion NOTE - In the case of torsional stiffness, 'force' and 'displacement' respectively are replaced by 'torque' and 'angular displacement'.

### Stiffness

Measure of resistance of plastics to bending. It includes both plastic and elastic behavior, so it is an apparent value of elastic modulus rather than a true value. (ASTM D-747)

### Stiffness

Stiffness is the ratio of change of force (or torque) to the corresponding change in translation (or rotational) deflection of an elastic element. Stiffness is often defined with respect to static or dynamic loading conditions.When a force is applied to a structure, there is a displacement in the direction of the force; stiffness is the ratio of th...

### stiffness

the resistance of a structure to deformation. Under a given load, the higher the stiffness of an implant then the smaller its deformation, the smaller the displacement of the fracture fragments and the lower the strain generated in the repair tissue. Excessive tissue strain can interfere with healing. The stiffness of a structure is expressed as it...
