Does the XYZ coordinates change for 1D elements, What does this based on?

Balasubramanian Dhandapani

 

In my understanding, When modelling a 1D bar element, the XYZ coordinates are based on the System collectors.

As you can see the common XYZ axis in the bottom left and the XYZ axis on the 1D element.

Does this mean when I'm looking at results(for example shear force at each axis (X,Y&Z)) do I have to assume the Y result of 1D element means X is real-life conditions?

Just trying to understand this coordinate system relations, so whatever information I can get is much appreciated

Thank you.

Hello Balasubramanian,

1D elements (beam, bar, rod, etc.) always have their X-axis pointing from one node to another. Y and Z will determine the orientation of the beam section.

Beam stresses results are in their own coordinate systems, such as in this video: https://www.youtube.com/watch?v=bqJAzx6JaT4&t=79s
