What is the bending stiffness?

The bending stiffness ( ) is the resistance of a member against bending deformation. It is a function of elastic modulus , the area moment of inertia of the beam cross-section about the axis of interest, length of the beam and beam boundary condition.

Similarly, what is simple bending theory?

Simple beam bending is often analyzed with the Euler–Bernoulli beam equation. The conditions for using simple bending theory are: The beam is subject to pure bending. This means that the shear force is zero, and that no torsional or axial loads are present. The material is isotropic (or orthotropic) and homogeneous.

What is deflection of a beam?

In engineering, deflection is the degree to which a structural element is displaced under a load. It may refer to an angle or a distance. The beams used for frame work are selected on the basis of deflection, amongst other factors.

What is Y in the bending equation?

Simplifying and rearranging gives, This equation gives the bending normal stress, and is also commonly called the flexure formula. The y term is the distance from the neutral axis (up is positive). The I term is the moment of inertia about the neutral axis.
