Bending stiffness
From Wikipedia, the free encyclopedia
The bending stiffness is equal to the product of the elastic modulus 
and the area moment of inertia 
of the beam cross-section about the axis of interest. In other words, the bending stiffness is 
. According to elementary beam theory, the relationship between the applied bending moment 
and the resulting curvature 
of the beam is
where 
is the deflection of the beam and 
the coordinate. In literature the above definition is sometimes used with a minus sign depending on convention.
Bending Stiffness in beams is also known as Flexural Rigidity.
