    How use nodal force (NFORC) to replace the surface stress by an equivalent surface traction.

    Dear to everyone, I have a model where I introduce surface residual stress value in 0.4mm. These values is introduced in the integration point of the element (in this case C3D8R). Now, I would like to replace the surface residual stress by an equivalent surface traction. I mean, I would like to...

    Problem with model change and remesh in abaqus.

    Dear, I am trying to carry out the following steps in my model: - Model.inp: remove one area of the piece with model change. - Inport the model.odb with file/import/part deformable stage, choose steps. - Remesh the model. - Generate new model and remove other area with model change. But I have...

    Section & Integration Points in S4R elements. SIGINI RESIDUAL STRESS

    thread799-326356 Hello to everyone, I am trying to introduce residual stress in the shell elements by SIGINI. This thread is about Section Points and Integration Points notation in shell element and coordinate system. To introduce residual stresses in the shell element through the thickness...

    ALE adaptive meshing (non-adaptive node problem)

    Helllo, Fist and foremost happy new year!!! Sorry for the late reply.I define eulerian surface in the the surface where flow enter and exit. But when I defined the nset to define enter and exit zone of the flow I did not consider the nodes of the corner or border because if you consider this...

    ALE adaptive meshing (non-adaptive node problem)

    Hello, I don´t know if this may help you but I avoid the problem of "Spatial adaptive mesh constraints can not be specified on nonadaptive node" defining the surface as Eulerian Region. You have to write in the .inp archive that the surface you used for ALE has to be Eulerian region. But still...

    Problems to mapp stresses in membrane element (sigini)

    Dear, I am trying to introduce initial reidual stress in the surface of my piece. I am doing that with sigini subroutine. I introduce in shell elements the residual stresses by KSPT (Section point number within the current layer.) I have never use membrane elements and I do not know if it is...

    How introduce with sigini stress values in boundary layer mesh

    Hello Mustaine, First and foremost, thank for your suggestion. I can aplly tthe stress value over the surface. But now I am working with more difficult geometry and I have one problem with normal orientation. I do not know if you can help me. I would like to introduce stress value over a...

    URGENT:How define the same normal direction of irregular surface in order to map stress by sigini

    Hello to everyone, I would like to introduce stress value over a irregular surface. My intention is that I would like to introduce stress by SIGINI subroutine. My proble in that I would like to introduce in Z direction 200MPA and in Y 50MPa, but I do not know how can I do that in irregular...

    ERROR in Eulerian adaptive mesh domains in Abaqus/Explicit

    Hello, I am trying to modelate induction heating process. Now, I am doing mechanical analysis, after carried out electormagnetic and thermal analysis. I am carring out the analysis in Abaqus explicit. This analysis, I think if I were not wrong, it could be steady stationary and I have to...

    How introduce with sigini stress values in boundary layer mesh

    Hello to everyone I trying to introduce machining residual stresses in the final piece surface. I have read some article which said that they mapped the residual stresses with 3 discrete subsurface layers into all machined surface. I understand they employ boundary layer mesh in Abaqus in order...

    How can I introduce velocity in thermal analysis

    Dear Mustaine, Thanks a lot for your suggestion, I will try to do it. In the other hand, now I am trying to introduce movement effect with mass flow rate case. I have read in abaqus documentation that when the problem is uncoupled problem you can introduce the movement with mass flow rate. I...

    Is it possible mapp residual stresses in C3D8S or C3D8HS elements?

    Thanks a lot. I will do that but before I have to install abaqus 6.16 because in abaqus 6.14 this elements is not supported. Once again, thaks for your answers.

    Is it possible mapp residual stresses in C3D8S or C3D8HS elements?

    Thanks a lot. I have doubt if I can employ SIGINI subroutine with C3D8S or C3D8HS elements. I know that I can use SIGINI to mapp the residual stresses with C3D8 elements but I have doubt if it is posible with this new elements. Once again, thanks for sharing with me your knowledge about abaqus.

    Is it possible mapp residual stresses in C3D8S or C3D8HS elements?

    Dear, I am working in milling process, it is the first time that I am doing something like this. I would like to mapp the residual stresses over the model. I read, abaqus 6.16 has new elements, c3D8S or C3D8HS linear brick elements, which provide superio stress visualization on the element...

    Electromagnetic-thermo-mechanic analysis by Abaqus

    Dear to everyone, I solve the problem of mapp Eddy current. The problem was that the coordinate system was not the same. But still I do not know how apply movement in the electromagnetic problem. Does anyone know how to do it? Thanks in advance to everyone. Regards, Ane
