    ABAQUS - Wall System

    I'll check that out, thank you.

    ABAQUS - Wall System

    So it seems to me the best way to model this would be in 3D, at least that is my understanding. However, as I've been researching this issue, it seems like 3D elements do not have rotational DOFs, which may be a problem since shear/bending are more important to me in this wall system.

    ABAQUS - Wall System

    Oh ok, I wonder if plane strain would work. I am interested in the shear behavior on the column. I will look into plane strain on Abaqus.

    simple stress/strain validation

    The problem is, I have been unable to determine the cause of this problem. I have read other posts and articles about this problem but to no avail.

    ABAQUS - Wall System

    The problem with a plane stress problem is that it requires the thickness (z-direction) to be very small compared to the X-Y dimensions of the object. But my column has dimensions of 18x120x12 (x,y,z or width,height,depth), which as per my understanding ], would not be applicable to the plane...

    simple stress/strain validation

    Would the following error: "The plasticity/creep/connector friction algorithm did not converge at # points" entail that the incorrect element type is being used for the expected deformations?

    simple stress/strain validation

    The above posts have actually helped me solve some of the problems I am having with my model that I discussed in this thread: http://www.eng-tips.com/viewthread.cfm?qid=345657 So I would like to thank you for that. I have been also to confirm my stress-strain data for compression and tension...

    ABAQUS - Wall System

    I am attempting to model this wall, now in 3D so that I can get more presentable results, since when I am modeling in 2D it does not show the thickness of the column or walls. I have a few more questions if that would be okay. 1. Is there a way to model that above wall system in 2D but show the...

    ABAQUS - Wall System

    I've been trying to learn ABAQUS by doing simpler setups, for example I have attempted a steel rod tension test or a concrete column (square) compression test, however, I am struggling a bit with getting acceptable results. 1. The material is concrete, so I would hope that it would be "simple"...

    ABAQUS - Wall System

    Hello, I am thinking about modeling a wall system. The wall system will consist of a reinforced concrete column in between two masonry infill walls. As shown here: I wish to investigate the effect that the masonry infill walls have on the column due to the fact that the walls do not go up...

    ABAQUS - Steel Rod Tension Test

    Hello again, These are now the new results I am getting when increasing the output frequency: ABAQUS: Strain / Stress 0 / 0 0.000744291 / 60460.3 0.00224891 / 61136.1 0.00450245 / 62148.3 0.00784938 / 63988.1 0.0128502 / 66867.8 0.0203003 / 71398.5 0.0313252 / 78655.2 0.0477414 / 87593.5...

    ABAQUS - Steel Rod Tension Test

    Thank you very much for your reply, as I have been stuck on this problem for days. Forgive me if this question may sound stupid, but how would I go about getting more output in the linear region? Thank you again for your reply

    ABAQUS - Steel Rod Tension Test

    To clarify my problem, I am applying a displacement to determine the elastic and plastic behavior of the rod through the stress-strain curve, but I get different values for the slope in the elastic region. Changing the displacement also has a large effect on the linear (elastic) portion of the...

    ABAQUS - Steel Rod Tension Test

    Hello, I am a very new user to ABAQUS and I am attempting to do a simple tension test on a steel rod to see if I can match up my theoretical stress-strain curve to the one being output by ABAQUS. My steel rod properties are as follows: Density: Density = 0.000730 lb-s2/in2 Elastic: Young's...
