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 ?
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],

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...
I have written below a code in python to extract data (PHILSM values) from the output file (.odb) at Time increment=10.
How to write a recursive loop in the code in order to extract data (PHILSM values) from the odb.file for Time increment 0, 1,2,3,..., 100 ? Thank you.
from odbAccess import *...
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 ?
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 ?
I want to define a transient internal pressure in a pipeline using an input file and the subroutine 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

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)...
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 ?
In 'Abaqus 6.13',
It is possible to insert a new step after initial. The step-1 can be editted to change the incrementation size, etc..
1-I would like to know which type I need to use when I create 'step-1' in order to study the coupling 'crack propagation/temperature' in a pipe ?

Hello,
1-I would like to know which feature I need to use in 'step1' in order to study the coupling 'crack propagation/temperature' in a pipe ?
2-Is it appropriate to study a propagating crack with the feature 'static,general' in step1 ?
Thanks.
I would like to couple the temperature field and the crack propagation at the surface of a pipe.
1)For the crack propagation, I use Step>Static/General. This cannot be used to study the temperature field and the impact of the temperature on the dynamic crack.
2)For the displacement of a...
