    Ductile materials

    Hello, What is the damage criterion available for ductile materials to choose with the XFEM method ? Thanks.

    Ductile fracture initiated by crack

    Is it possible to simulate a ductile fracture initiated a crack using a XFEM crack and a traction separation law for the material damage initiation criteria ?

    Write frame.description in a text file

    How to write in a text file the following data: Increment 0: Step Time = 4.2613E-06 … Increment 100: Step Time = 4.2613E-04 I used the code: file.write('%s %d %s %s %6.4f \n '(frame.description[0], frame.description[1],frame.description[2],frame.description[3], frame.description[4])) I...

    How to write the Frame description in a text file ?

    How to write the frame description, Step Time and Time increment in a text file ? I tried the following code but it does not work. file = open("/directory/newfile.txt","w") for frame in odb.steps['Step-1'].frames: displacement = frame.fieldOutputs['PHILSM'] for y in displacement.values...

    Extract data from .odb file for each time increment of Step-1

    In the last line of the program below, what is the keywords to put instead of frame.description[1] and y.frame.description in order to display the name and value of Step Time in order to have on each line: the TimeStep, Node and Philsm values for frame in odb.steps['Step-1'].frames...

    Extract data from .odb file for each time increment of Step-1

    I tried the code written below but it does not work. I want to extract the PHILSM for each frame for stepName in odb.steps.keys(): print stepName step1 = odb.steps.values()[0] print step1.name #These two lines below work ok and display each frame with their values for frame in...

    Extract data from .odb file for each time increment of Step-1

    I wrote the code below in order to display the frame names, but get the error message 'expected an indented block'. What would be the appropriate code to display each frame ? allFrames = odb.steps['Step-1'].frames.keys() for j in range(len(allFrames)): frame=odb.steps['Step-1'].frames[j] print...

    Dynamic XFEM crack: PHILSM function and time increment value associated

    How to extract the frame (with time increment value) associated to the crack front position in python ?

    crack path

    I want to extract the position and the time at which a XFEM dynamic crack occupies a certain location. Is step-1:0 to 10 gives an indication about the time ? How is represented (coded) the time in the odb. file ?

    XFEM crack: static/general versus dynamic/implicit

    What is the difference between 1) the static/general procedure for step-1 and 2) the dynamic/implicit procedure in the case or a XFEM crack ? Is the time taken into account in the results generated from the first procedure ?

    Transient internal pressure

    To test the dload subroutine, I modelled the pressure by two ways 1) Using the input file with the loads written as: ** LOADS ** ** Name: Load-1 Type: Pressure *Dsload Surf-1, P, 7000. ** 2) Using the input file with loads written as below and also using a dload subroutine: ** LOADS ** **...

    Transient internal pressure

    ...DLOAD 1) I use as a starting point the input file at constant pressure: I use the file.inp as an input file. The loads are defined as: ** LOADS ** ** Name: Load-1 Type: Pressure *Dsload Surf-1, P, 7000. ** 2) For the transient internal pressure, I modify the load part in the input file...

    Ductile fracture-enriched element

    I would like to study a ductile fracture. In this purpose, I have defined the geometry of the model plus a XFEM crack. I have defined the three following features in the "Material module": 1-Elastic: (Young’s modulus and Poisson’s ratio) 2-Plastic: (Yield stress and Plastic Strain: 8 lines)...

    Coupling crack/Temperature

    I am studying the propagation of a XFEM crack using "Predefined fields> Temperature".(Predefined Fields can be found just after 'BCs') I would like to know if the temperature has an impact on the crack behaviour in this case ? Is it a good way to do the coupling crack/temperature ?

    Crack propagation coupled with temperature

    When we study the propagation of a XFEM crack (with the procedure 'static/general' or 'dynamic implicit') using a predefined field>temperature, will the temperature have an impact on the crack behaviour (i.e. is there a coupling crack/temperature) ?

    Crack propagation coupled with temperature

    Is it possible to create a dynamic crack using XFEM ?
