    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...

    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...

    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

    Hello, I have done static thermal analysis and now I would like to introduce velocity to the tube. Is it possible to introduce velocity in thermal analysis? How can I do? Thanks in advance, Ane

    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...

    Problem with mass flow rate to introduce velocity in thermal analysis

    Dear, I am working with thermal analysis and I would like to introduce velocity to the tube. I am introducing the movement by mass flow rate, defining INPUT and OUTPUT node set. But, I have problem with the convergence. Any help it would be appreciated. Regards...

    How apply movement to tube

    Hello to everyone, I do not know if this is the forum to make this quiestion. If it is not the forum, sorry in advance. I am doing electromagnetic calculation and I have results, but the tube has not displacement. Now I would like to introduce the movement to the tube. I want to introduce...

    Electromagnetic-thermo-mechanic analysis by Abaqus

    Good afternoon to everyone, I am trying to simulate by Abaqus the induction heating method is employed in order to Weld tuve. I did the electromagnetic calculation and I transfer the Eddy current to the thermal analysis but I do not why the temperatura distribution is not adecuate. I mean...

    How modify sigini to apply in shell element

    Hello to everyone, I am using Abaqus CAE to model machinig. I want to include the residual stress (material and machining residual stress) into my model. Firstly I want to introduce homogeneous residual stress in Shell surface (I am using Shell element S4R and reduced integration). In the...
