    Linear Dynamic Model doing a harmonic study measuring relative displacement between two points

    I actually figured it out I had to right click the results in the feature tree and it had the an option for response graph or something along those lines that was nowhere else to be found. That has an option for phase angle.

    Linear Dynamic Model doing a harmonic study measuring relative displacement between two points

    Hi doing a harmonic analysis and I want to know the relative displacement between to points on my structure. I have not been able to find a method to either get the relative max distance for the frequency graph nor find the phase angle. If anybody can help that would be great. A little back...

    Purely plastic analysis

    If you are having large deformation you may want to try explicit step. A little more description of your set up and maybe a picture may be helpful. But I do not know how to solve this I am relatively new to abaqus.

    Tied vs Partition inorder to have 2 layers connected

    I ran a simulation that took a while but dropping the density in the tied model did solve my problem. Does anybody know why this worked I would really appreciate any insight you may have into this phenomenon. But for anybody who may work on a project and has a problem with tied vs partitioned...

    Tied vs Partition inorder to have 2 layers connected

    Could the problem I am having be caused by density? I have been playing with the density and it seems like it is causing some what closer results but nothing I can be positive about? Does anybody know if Density is treated differently when an object is partitioned vs tied? I am wondering if for...

    *Tie versus *MPC, pin

    I have never used a preprocessor but I am having a similar problem to this , see http://www.eng-tips.com/viewthread.cfm?qid=410218. Could you use a preprocessor to merge the nodes and still assign the two sections their own material properties? Thanks, Campbell

    How apply movement to tube

    Have you tried setting the BC>Mechanical>Velocity/Angular velocity?

    Tied vs Partition inorder to have 2 layers connected

    Yes Thank you Mustaine3 here is a link to a Google folder I made with 3 different case files. One file is of my geometry partitioned apart. One is of the two sections merged together and one is of them not merged together. They should all already be meshed and setup to run in one form or...

    Tied vs Partition inorder to have 2 layers connected

    That is one of the setups that did not work. I tried running just tie constraint again and got a very similar result to this one. In this you can see that it is forming spikes instead of building up pressure and then bucking This is what I get when i partition the two layers out of a single...

    Tied vs Partition inorder to have 2 layers connected

    It appears that my problem is that the only way that I can get my parts to deform together is by using partition in all of the other methods I have tried my base layer does not deform with my surface. I am wondering if my problem is that some how my surfaces can slide across each other. The...

    Tied vs Partition inorder to have 2 layers connected

    Yes my two parts are deforming together. My outer layer is slightly stiffer then my inner layer. I am using abaqus explicit my densities are the same. And I expect relatively large deformation. My test case is on a half sphere where the outer layer has thickness of 2 and inner layer has a radius...

    Tied vs Partition inorder to have 2 layers connected

    I am building a model where I have two layers of material. The outer layer is growing faster then the inner layer in my model. When I use partition to separate my two areas everything works great and I get the results I expect. However when I use the tie function, iterations or merged assembly I...
