Bending Stiffness
Simple Cantilever
The expression will be given in terms of stiffness per unit width
𝛿 =4 ∙ 𝑃 ∙ 𝐿3
𝐸 ∙ 𝑡3
Where:𝜹 Deflection in the direction of the force vector, in𝑷 Force applied, lb𝑳 Original length of the cantilever beam, in𝑬 Young’s modulus of the member material, psi𝒕 Thickness of the beam, in
The expression for Stiffness can easily be derived as
𝑘 =𝐸 ∙ 𝑡3
4 ∙ 𝐿3
