Stiffness (K) is a measure of the force required to produce a unit deflection in a structure or material. It indicates how rigid or flexible a structure is when subjected to an external force.
Formula for Stiffness (K): The formula for stiffness in the context of a spring or an elastic element is given by:
where:
-
- = Stiffness (in newtons per meter, N/m)
- = Applied force or load (in newtons, N)
- = Deflection or displacement caused by the force (in meters, m)
