    how to find the exactly Young's modulus of an assembled model ?

    Hi all, I was given a 2-D tire model in abaqus. It consists of Bead, Cap ply, Steel belts, Rubber (tread), Rubber (sidewall). I want to know what the young's modulus of the whole tire is but I do not know how to. I can only find the young's modulus of all the components in the material...

    contact problem of adding load on a tire model to see its deformatiom

    Hi Mustaine3, Thanks for your replying. I mean if the road is moving towards the tire, the tire would have some pressure changes and it would eventually buckle at a critical load and this is the main aim of my simulation. The tire should change to barrel shape but instead it seemed the tire...

    contact problem of adding load on a tire model to see its deformatiom

    Hi Mustaine3, Really thanks for your reply. I have changed the load directions and the BC for the top rigid road and also added some friction the hold the tire. The analysis is completed now. In the ODB file,I can see the tire deformed now, however, the there is no any pressure changed in...

    contact problem of adding load on a tire model to see its deformatiom

    Hi Mustaine3, Not sure if you have seen my reply yet. Therefore I reply again to hope you can see it and give me some advice. Thank you very much. Best Regards, JAY

    contact problem of adding load on a tire model to see its deformatiom

    Hi Mustaine3, Thank you for your reply. I tried to add some boundary condition for the rigid road 2. And now the overclosured problem is solved. The tire is supposed to buckle when the load is applied on the road. However, the tire did not buckle and it became sliding this time. Therefore I...

    contact problem of adding load on a tire model to see its deformatiom

    Hi Mustaine3, You mentioned that I should use the negative side of that face for contact. Does it mean I hsould change the SPOS to SNEG? I tired it but it did not work. The road2 has become sliding after this. I also looked into the the meaning of the data line in the section of *Surface in...

    contact problem of adding load on a tire model to see its deformatiom

    Dear Mustaine3, I have checked the normal of the road2 and I found that the direction of the normal is in wrong direction! Could you please tell me how to change the direction of the normal in input file? Or is there any other solution to deal with this situation? Thank you very much...

    How to change the direction of normal in input file

    Hi all, I created a 3D tire model and 2 plans as the roads in input file. One of the 2 plans is in contact with the bottme of the tire, another one contacts with the top of the tire ( just like a burger, the tire would be the steak and the 2 planes would be the bread). However, I found that...

    contact problem of adding load on a tire model to see its deformatiom

    Hi all, I am trying to do the simulation of lying a tire model on the ground horizontally and adding load on its sidewall to see its deformation. I have already had my 2D tire model and it runs well. I think there is something wrong in my 3D input files since the msg file keep showing the error...

    CPSET in CLEARENCE command

    Hi all, I am trying to do the simulation of lying a 3D tire model lying on the road horizontally and adding load on its sidewall to see its deformation. However I think there is a contact problem in my simulation. When I run the analysis, the analysis did not complete and it showed an error is...

    Contact problem between a tire and the road?

    hi fauzi2015 Thanks for your reply. However, since I am a rookie in abaqus and this is for my final year project and my supervisor gave me the input file and asked me to modify to get the result, could you please explain more specifically about how to lower minimum time to convergence, enter...

    [Abaqus] Problem with msg error?

    Hi all, I am running the simulation about a tire lying on a road and adding load on the sidewall of the tire. I was given a tire model which the tread of the tire was in contact with the road. Then I made some changes in the 3D input file to make the sidewall of the tire...
