    Cam-Clay Material Model Example?

    Hi all! As part of one of my projects I will be required to conduct a settlement model with the use of cam-clay modelling in the soil. Having had zero experience in soil mechanics, I am struggling to get to grips with all the terminology and finding a complete data set to try a test run of my...

    Easy question about a *Dload

    Hi gents, I have a quick question as I am starting to doubt myself. I have a download which I am increasing over the space of 3 steps by using the op=mod card for the dload like so; Step 1: *dload, op=mod nodes, pz, -2000 Step 2: *dload, op=mod nodes, pz, -9000 Step 3: *dload, op=mod...

    Modelling a rope/chain connection

    Hi all, The problem I am looking to solve is what type of elements to used to simulate a rope connection between two concrete blocks. An example of what I am modelling is below. I have done some searching but to no avail. I am not worried about any data from the rope; I just want to simulate...

    Applying a torque to a kinematic coupled reference point

    I am trying to apply a braking torque to the centre hub of an alloy wheel (i have posted before if you have seen already) I have the rear of the hub kinematicaly coupled to a reference point at the centre of rotation. Is there a way of applying a troque to the reference point to give the center...

    Rotational displacement BC problems

    Absolute hero ! Thank you so much for the help IceBreakerSours. Everything is working as it should! Out of curiosity, where is it running my inp. file with that command as it says there is 90 licenses and i only have acces to 14 usually ?

    Rotational displacement BC problems

    Cheers for the help. I got it working but used reference point as my 'ref node'. My issue now is with the symmetry conditions as my cyclic symmetry does not work, it just crashes as soon as the job is submitted. It is something to do with hardware acceleration apparently but i already have it...

    Rotational displacement BC problems

    OK so should this be my process? Do i select UR3 since this is the degree of freedom that i was the rest of the nodes to copy? Then select the ref node again to apply the rotation Thanks for all your help, this is for a final year project and iv never used ABAQUS to this extent before.

    Rotational displacement BC problems

    This is a very short video i took of my first simulation that worked, it shows what i want to achieve.http://files.engineering.com/getfile.aspx?folder=b43b664f-846d-4b67-90a0-13bab30f0b7f&file=toque_.avi

    Rotational displacement BC problems

    sorry if i have been unclear my knowledge of abaqus is very limited. According to the literature 3D elements do not have rotation, but im not trying to rotate the elements just apply a displacement to their position around an axis (Z). This is the reason why im confused about the error im...

    Rotational displacement BC problems

    PS. Please ignore the terrible mesh, i do intend on refining it later on

    Rotational displacement BC problems

    Hi all, I am trying to apply a rotational displacement to a wheel which has been sectioned into 1/4. I have modeled this before so i know its possible, my issue is that it will not work again even with the same BC's etc. I basically have 1/4 of an alloy wheel with the outside rim surface fixed...

    Cyclic symmetry trouble

    Hi, I am modelling 1/4 of an alloy wheel in abaqus/CAE and i am using the cyclic symmetry option in the interactions. My issue is that it will allow me to select a master and slave surface but when i want to select the axis of rotation it will not allow me to select the datum axis i have...

    How to prevent rigid body penetration; Rigid body compression deformable body

    I shall try try too, i originally thought of using an analytical surface but initially it started off as a 3d part then i reduced it to a surface part. I suppose now that it is essentially a surface then using analytical surface would make sense. Should i be using a self contact interaction too...

    How to prevent rigid body penetration; Rigid body compression deformable body

    This is my first post here but have used it a lot to help with my project. First let me explain what i am trying to achieve here. I am physically testing half an alloy wheel under a compressive load to validate my Abaqus model. The load is dependant on the displacement of the striker by 20mm...
