Dear All, I have a question regarding importing material orientations. I perform analysis in two steps: 1) In the first step, boundary conditions are applied and the model is deformed. 2) After the first step I import the part into a new code (along the with the stress state), impose a TIE...

Dear all, I was wondering if it is possible to do the following in ABAQUS. 1) Run simulation A with specific Boundary conditions. 2) Create a fresh simulation B where the input is the output of simulation A. Here I want to impose a TIE constraint. 3) Run simulation B. Any suggestions on how...

Thank you all for your suggestions. @yaston4: I tried some of your suggestions. I always get that error. Basically, if the two surfaces share nodes (which they do), it looks like it does not matter what the other external conditions are. @DanStro: I was thinking about doing exactly what you...

Dear All, I am trying to define a "SurfaceToSurfaceContact" interaction between two surfaces which have a common edge. Initially, these two surfaces are separated (taking a "V" shape). I apply Boundary Conditions to close the surfaces onto each other. In the next step I want to apply Contact...

My model is being elastically deformed (with NLGEOM=on) and consists of a twin boundary. I am new to the field of finite element simulations (and ABAQUS) and would like to hear your thoughts on how to incorporate the twin boundary. I am currently simulating the boundary in the following way...

Thanks for the valuable input. I was also thinking in the same lines of the comment by ESPcomposites. And my system has all parts that are comparable in length. I also observed that for a reasonable meshing i cannot go below 0.005 meters in ABAQUS. Thanks.

Dear all, This might be a simple question. What is the smallest length scale that can be simulated in ABAQUS. I am trying to run some continuum estimates for particles with dimensions in the nanometer range (10 to 50 nm). Is it possible to specify such length scales in ABAQUS? Thanks for your...

Dear all, I am wondering if it is possible to impose a symmetry condition in ABAQUS such that the final solution obtained has that particular symmetry. I am trying to model a wedge disclination in a 2D disc. The problem simply contains a disc with a pie (of certain angle \omega) removed. Then...

Thanks for all the suggestions. I was able to create a simple decahedral model by using the extrusion feature first and then by creating sections and deleting unwanted features. Thanks for the help and suggestions.

It is a solid model. An example of what I am trying to model looks like the decahedra shown in Figure 1 in this link. http://www.springerimages.com/Images/MaterialScience/1-10.1007_s11051-010-9865-x-0 This is an example but there are other models that are more complicated.

Dear all, Could anyone shed some light on constructing a 3D model in ABAQUS, which cannot be build by simple extrusion, revolution or sweep. I understand that I can build models in CAD and use it as an input for ABAQUS. The only other software I have is MATLAB. Any ideas on how I can build such...

Hi all, I am trying to use ABAQUS to study stress-strain distributions in a polycrystalline material. To this end, my first goal is to simulate elastic deformation (small strain) of a polycrystalline sample of an elastically anisotropic material. What I am looking for are some tutorials or case...

Thank you very much for your suggestion. It worked !! Thanks, Rakesh

Dear all, I am trying to learn ABAQUS using this problem (what I thought would be simple enough): Initial Geometric Configuration: A Disc (thin) with a finite radius (1 unit) and a wedge (5 degree pie) cut off. It is basically a disc with material present only from phi = [0,355] and the...
