Hi
I want to modeling fatigue in composite with abaqus and i need a simple example in this subject.
can i help me?
tnx
Hi all,
I wanted to simulate fatigue crack growth in ls-dyna, obtain dK, crack tip stress fields. But I wanted to start from a simple model. I can't find any examples online, tutorial...
Hi,
I am trying to do Low cycle fatigue analysis in abaqus, and
according to the Documentation, for bulk material damage initiation and damage
evolution definition, I can use the criteria (and type for Damage evolution) as
"Hysteresis Energy". And have to define 4 material variables C1 to
C4.

But in the abaqus material library (in abaqus-CAE) i could find
all the other criteria but not the "Hysteresis energy". I also tried
to define it in the *.inp file but abaqus could not read it (apparently wasn't
writing it correctly).

All,
The deadline to submit article for the CSME international congress has been extended to February 17th, 2012. We are organizing a symposium on fatigue and fracture of engineering materials and strongly encourage researchers around the world to submit their research articles relevant to this field.
More information can be obtained from the following website: http://umanitoba.ca./engineering/conferences/csme2012/index.html
i got three questions here.
1) If im using ANSYS, how am i gonna do a fatigue life prediction of a welded joint? The speciment is butt joint. I need to know the procedure.
2) If im using ANSYS nCode DesignLife, how am i gonna obtain the SN curve if im using FE Model or Multi-column?
3) If Im using ANSYS nCode DesignLife, what should i pick for the geometry if im doing on CTOD method of a butt joint welded speciment?
Thanks for the help. :)
After a long process (somebody may recall I made also quite some chaos on imechanica to complain with the review process in a previous journal), this paper was accepted. Ask me a preprint if you are interested. I can attach here a few images only.
