What does stiffness mean?
Stiffness is an important concept in engineering and mechanics as it influences how structures and systems behave when subjected to different types of loads. For example, structures with low stiffness will bend or deflect more when under a given load than structures with high stiffness.
The stiffness of a structure is of principal importance in many engineering applications, so the modulus of elasticity is often one of the primary properties considered when selecting a material. A high modulus of elasticity is sought when deflection is undesirable, while a low modulus of elasticity is required when flexibility is needed.
As a key concept within solid mechanics, understanding stiffness is vital for engineers across all specialisms. This comprehensive guide offers a thorough definition of stiffness, its importance in engineering, practical examples, and examination of how to recognise it.
Bending stiffness is the ability of a structure to resist bending or flexure, while torsional stiffness is the ability to resist twisting. However, there are other types of stiffness that may also be important for specific structures, such as axial, lateral, shear stiffness and rotational stiffness.

Dec 16, 2016 · Stiffness is a measure of how much force is required to displace a building by a certain amount. If it requires more force to shift Building A than Building B, we would say that Building A is stiffer.
Stiffness is the capacity of a mechanical system to sustain external loads without excessive changes of its geometry (deformations). It is one of the most important design criteria for mechanical components and systems.
