cosa intende nastran per asse neuter?

Hello everyone!
as from title, I cannot understand what nastran means by neutral axis (neutral axis). The neutral axis is an axis lying in the plane of any section of the beam. However, in Figure 4-25 of the nastran documentation (clikka qui per vederlaThis axis is represented throughout the beam. Can anyone give me clarification?

before posting a question, since it is the first you should present yourself in the appropriate section.

in any case nastran means the axis that connects the center of the section to the node a and the center of the section to the node b.
assumes that a load applied along the director ab generates only tension and compression and not bending in the beam.

I understand thank you. Where could I read the info I asked?

I didn't understand the wave response, maybe because I don't know nastran. However, if in a section the neutral axis is what separates the compressed area from the traction area, it is also true that the set of these axes in the various sections originates the neutral plane. the intersection of the neutral plane with the sheet plane where the beam is drawn, is a new neutral axis that unites the centerpieces of the various sections.
