total deformata

[driver]

Hello, everyone.

Does anyone know how "ragiona" from the mathematical point of view this command of the solution? is the eq.ne of the elastic line (y derived twice compared to x = - m/ej) ?

Thank you.

Are we talking about fem?
in this case the concepts of "derived" and "integral" must be replaced with "subtracts" and "somme".

the total deformation is the sum of the movements of each element. each element moves according to the rotation of its previous node. each node contains the deformation of the element according to its position in the matrix of stiffness.

was that the question?

That was it, thank you. As for the clarification, you are right, I had written in terms of derivatives and integrals to make understand the eq.ne that I meant from the point of view of the science of buildings and not of the fem.
