    Crack propagation model

    Please try googling with keywords pertaining to the type of problem you are solving. Eg. Steel crack propagation abaqus damage criteria.

    Crack propagation model

    Hello sithlord382. You will have to specify damage criteria for the material. Goto Material>Mechanical>Damage for traction separation laws>Maxps damage. Or similar damage criteria.

    Crack propagation model

    I don't think you can apply loads on the crack surfaces through this approach. You can apply loads on the top and bottom surfaces of the cube.

    Crack propagation model

    Are you using XFEM crack propagation? If yes, the shell instance is suppressed after you define the initial crack using the shell. The surfaces would then be invalid for load definitions.

    Job file not writting section information

    If you are using element sets for section assignment, you might have to redefine the set/selection when you change the mesh of the part.

    Job file not writting section information

    No. I mean can you share what kind of parts and sections you are using? If you are using a solid part, it has to have a solid section assignment. If you assign an incorrect section to a geometry, it might give you an error.

    Job file not writting section information

    Do you mind sharing more information about this error message or the number of parts in your model and the section assignments?

    Job file not writting section information

    That's weird. Even if you submit a job within CAE, the input deck (*.inp) is generated and it is processed by the solver. So, if the *.inp is working within CAE, it should work outside of CAE.

    Calculation of Error in Abaqus - soil earthquake excitation

    Hello JoSpencer. In the post processing module, you can plot graphs, save them and then operate on XY data. I believe you can easily calculate the error measures using the operate on XY data feature.

    railway modeling

    Please find more information regarding periodic amplitudes in the link to the section in Abaqus manual below. Kindly go through the various sections in the Abaqus manual. http://www.egr.msu.edu/software/abaqus/Documentation/docs/v6.7/books/usb/default.htm?startat=pt07ch27s01aus93.html

    railway modeling

    Hey hbkhero. Try pressure load with a periodic amplitude.

    Wire Bending on Roller.

    Yes. Redefining the node set means reselecting the nodes for the BC. Instead of picking them during BC definition, I'd suggest creating them in the part module and then accessing them during the BC. That'd help with clarity.

    Changing material properties in Steps

    I am not sure if you can change material property from step to step. Do you mind sharing the posts you found regarding this?

    Time period problem in hot torsion simulation

    Assuming that you are running Implicit..I would initially run the simulation for a total time step of 1 second with a initial time increment of 1E-3 and a minimum time increment of 1E-6. Depending on the deformations, the time step would adjust itself through the simulation. The simulation would...

    ABAQUS Support Conditions

    For a simply supported edge, the beam is only allowed to rotate along one axis parallel to the edge. I'm not sure what you mean when you say continuous support.

    Meshing gears in Abaqus - contact analysis

    Hi vjantarajunior. Unconnected regions could either mean that the parts are not given appropriate boundary conditions or that solid regions in a part could be disconnected. I would suggest performing a check for any surfaces or solids with gaps and any degrees of freedom that are not constrained...

    Time period problem in hot torsion simulation

    Short answer is yes.

    Wire Bending on Roller.

    When you create a BC for a particular node region, you select it while defining the BC. That node set is saved by abaqus as *_pickedset. When you make any change at all to the mesh of the related part, the *_pickedset is invalid. You will have to check the boundary condition and redefine the...
