    Buckling of Hollow Tubes (counter intuitive results?)

    Hi, I have a space frame made from beam elements in Abaqus and am trying to find the buckling load. When all the beam profiles are solid there is no problem and i find an eigenvalue and also a LPF from Riks analysis, I have checked this with a simple single beam also to check my method...

    Riks analysis using Eigenvalues

    I am having some trouble with a Riks analysis, I have gone back to basics to try and get the correct results and have modelled a simple circular bar with 10 elements along its length. I have found from Eigenvalue buckling an initial mode at 23.479kN after applying a 1N load to the top and...

    Remeshing once the .inp file has been edited

    Hi Guys, Think I may have a small gap in my understanding. Basically I have created a 3D space frame in abaqus the shape of a Buckyball, using beam elements. I have meshed the part along the edges using 1 element for each beam. I then edited the inp file to add some internal bracing to the...

    Creating a Buckyball In Abaqus

    Thank you sdebock very kind of you. Looks the same as the model i created, I assume it will use wire connections too then? I will try and install it on one of the Uni computers as I don't have linux myself. Seems like a good thing to research and add in to my project.

    Creating a Buckyball In Abaqus

    Thanks very much for your help, I am not very experience with Abaqus and have no knowledge of Python which is why i am being slightly tentative. But I saw a video using some wires and some sketches on planes so I thought why not use all wires. The assembly is actually relatively quick as I have...

    Creating a Buckyball In Abaqus

    Hi Guys, For my fourth year project I am trying to create a Buckyball, otherwise known as a C60 element in Abaqus. I have modelled the structure in Solidworks but unfortunately do not have the licence available to create enough nodes to analyse this in Abaqus. I am fairly new to the software...
