low cycle fatigue

Is the study of Low Cycle Fatigue (LCF) and cyclic plasticity useful for biomedical metals?

I would like to open a discussion in relation to the following question:

"Is the study of Low Cycle Fatigue (LCF) and cyclic plasticity useful for biomedical metals?"

It appears that there is some level of misunderstanding around this issue. Thus, I would be very interested to find out the views of iMechanica community engineers and researchers working on biomedical metals and applications (i.e. implants) on this.

Abaqus Low cycle fatigue - Hysteresis Energy Criteria

Submitted by sidd04mech on

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.

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).

Modeling fatigue crack growth in abaqus using xfem

Submitted by m.kesh on

Hi

Dear all,

I am new to abaqus and I have to model a fatigue crack growth using xfem.

I have searched for a tutorial for that and I could not find anything useful. 

Does anybody know where can I find the tutorial or smth helpful?

tnx in advance,

 

LOW-CYCLE FATIGUE CRACK PROPAGATION IN ABAQUS USING XFEM

Submitted by Alberto.Garcia… on

 

Hi all,

 I´m traying to simulate a low-cycle fatigue crack growth in Abaqus 6.9 using xfem. My problem is to add the low cycle method to the xfem solution. 

I believe that the only current option for this would be to manually
create the loading curve and to do the analysis by a brute force
method but i may not be correct in this assumption however.

Please could someone explain a brief method.

i appreciate in advance.
