Thank xref for your answer, I understand and agree with you for the energy balance. For the problem elastic crack propagation, all quantities ALLKE, ALLVD, ALLVD, ALLSE , ALLPD , ALLCD , ALLAE are zero. (Fig. 1) Fig.1 : Energy quantities zero I obtain: ALLIE=ALLSE this relation is...

I have an elastic crack propagation analysis using slave-master method with crack length time-dependent criterion. It works fine unless I can’t find the balance energy between internal energy and work external like the following (ABAQUS Theory Manual/Energy Balance 1.5.5) If we note : ALLWK...

Does anyone known why the Crack propagation analysis can't be performed using the *VISCO procedures in version 6.6.3 but this can be done with version 6.4 ? It's a only backwardness ? :D ( ABAQUS Analysis User's Manual - 7.10.3 Crack propagation analysis ) Thanks

Thank you for your pertinent answer that I’ve waited and checked for for every hours ;)). And I have some remark following : I think stress intensity factors (SIFs) make sense only for linear elastic materials. I agree with you that the SIFs is used in linear elastic fracture mechanics, but...

In order of studying a crack propagation analysis of viscoelastic material (bituminous binder), I use crack length versus time criterion for my model of CAX4 elements that you can see in the image: When I calculate the stress intensity factor and opening crack factor by extracting the...

With Python scripts, you can automate any post-processing :D see more the docs "Scripting User's Manual" www.aevn.fr

We have to put the "!" before the same command in MS-DOS (cmd/command) to run ABAQUS. For viewing the results, you can use : !abaqus viewer database=path/jobname.odb For exemple : !abaqus viewer database=E:\ABAQUS\work\maer\meshca_maer.odb It worked. Thanks

@ohagan : How do you run ABAQUS job in matlab ? Do you use the DOS command ?

In fact, I have a viscoelastic material in Prony-series presentation by fitting these models to viscoelastic experimental data. . At the moment, I have to determine the property of this model Prony-series for each temperature and following by a calculation of this file input abaqus *.INP. But I...
