The Study by Mr. Wu etc Concerning Saint-Venant’s Principle is Insignificant

The paper titled "The Study by Mr. Wu etc  Concerning Saint-Venant’s Principle is Insignificant" reviewed the series of four works of “proof of Saint-Venant’s Principle” published by Wu etc .The four articles proved neither the discrete Saint-Venant type decay of section-forces of the finite elements in the chain model of discretization of the cylinder  nor  the discrete Saint-Venant-type decay of section-displacements, posed in their papers. Furthermore, the discrete Saint-Venant type  decay of section-forces  is not provable.  Nevertheless, the proposition of the discrete mixed Saint-Venant type decay of  the cylinder was discussed in Wu’s articles  by taking the “super” forms of the two single decays mentioned above as a priori assumptions, and so the discussion is of uncertainty, or meaningless, for  proof of Saint-Venant’s Principle. See the attachmentst for the details.
