Abstract

 

In the state picture element with the postcode secheniem s 3 step step. Each node consists of 3 displacements, two (ω, φ) are formed by bending, and the third (u) is formed by longitudinal force. It was found that small deformations do not take into account the effect of longitudinal forces on the finite element on the transverse bending. This is due to the fact that longitudinal displacements at the nodes do not affect the reactions of additional nodes caused by bending displacements (ω, φ).
