When applying a pretension of, for example, 1e6 N to anchor cables in ABAQUS CAE, should one use 'bolt loads' or 'Defining an initial stress'? Or neither of these? The results mentioned above were obtained using the method of creating and editing bolt loads.

In the Abaqus system shown in the figure, three analysis steps are set up: step1, step2, and step3. In the step1 static analysis step, a pretension is applied to the top of six anchor cables. In the step2 static analysis step, net buoyancy is applied while the pretension remains unchanged, and...

For a general section beam element with eccentricity, if the output point is set at the centroid position z=-1, will the line load be loaded at the centroid position z=-1 or the beam element position z=0 on the diagram?

Why are the element stress values obtained using the PYTHON code different from the element stress value obtained by querying directly in the CAE interface? The code is as follows: odb = session.openOdb('odbname', readOnly=False) ele =...

Thank you for your help. I understand the difference

I would like to ask a question about internal forces in section: in ABAQUS, the output results of internal forces in section of beam elements (SF1,SF2,SF3,SM1,SM2,SM3) are obtained based on the local coordinate system. Are these 6 components based on the local coordinate system that was not...

I would like to inquire what is the difference between the two connections below? (1) With a connecting beam in the center, the end points of the connecting beam are connected with beam connectors; (2) Without a connecting beam in the center, the two points on the beam are directly connected...

Why is it not possible to output the connection force of a rigid connection of multiple separated lines using ABAQUS CTF? I wonder what the problem is besides? Even though the output CTF is set in the field output, I can't find the CTF in the ODB file, or all the CTFs and CTMs are 0. What is the...

Thank you very much for your answer. I forgot that I could restart ABAQUS. After restarting ABAQUS my problem was solved.

Question: What is this thing in the sketch? I didn't draw it, it's unnecessary, but I can't delete it

in ABAQUS help document, it is "Element-based results for beam and truss elements cannot be transformed; they are always displayed in the local element orientation system. ". In the figure below, when the beam element has a large displacement, the local coordinate is which of the coordinates...

No, it is not the apllied load. The applied load is on the concentrate force which is 1e7 N in the top of the free section. Yes, the values in the table refer to the reactions of the support. Even though I tried a simpler 3D beam model, the model still has a small reaction force in the...

Thanks for the answer. Because I tried to load the cantilever beam with the same equivalent force for the combined forces, I found that these tiny amounts are not equal at the supports. Although this is a small order of magnitude, I wanted to explore what this small amount is due to. According...

In ABAQUS, is the SF and SM of the nodes output from the beam model based on the post-deformation beam local coordinate system or the pre-deformation beam local coordinate system. If it is a post-deformation beam local coordinate system, does this mean that the orientation of this coordinate...

1. In ABAQUS, for a three-dimensional cantilevered cylinder structure, there is only a force in the Y direction at the top of the free end, so why is there a branch reaction force in the X and Z directions at the solid end (with all six degrees of freedom constrained)? 2. The support reaction...
