hi.
I am working on " crack emanating from a circular hole in anisotropic medium". now i got the K1 ( SIF`s) using complex stress potential method. Now i want to represent the results in the form of stress field around the crack.
i am unable to find the stress field around this crack.
i request you to hint the procedure to plot the stress fields.
thanking you.
Yours Sincerely
vinay.
Hello everybody,
my question regarding how can calculation stress/strain field as well as good agreement with experimental results? espesially in crack tip and the behind of crack trip?
thank you for your help in advance
Hadi
measurment of FCG based on crack tip closure concept depend on :
1- experimental technique
2-location of the measurement
3- mean stress effect on FG at high stress ratio can not be explained by the closure model due to the absense of the crack closure at high loads.
Two question can be investigated as follows:
1- why crack tip closure is popular and it widely use in hightech industry like aircraft industry acording to overwiew of scentific articles.?
hi all,
I am a mechanical engineer currently pursuing Master degree (Post graduation). Ultimately i also want to pursue a research leading to PhD after my master's. Its my burning desire to do some significant research in the field of Fatigue analysis using Fracture mechanics approach preferably for aerospace domain using advanced CAE softwares like Nasgrow, Afgrow, Abaqus, FE-safe, MSC Fatigue, etc,..
Dear Colleague,
the IV European Conference on Computational Mechanics-ECCM 2010, Solids, Structures and Coupled Problems in Engineering, organized by ECCOMAS, will take place in Paris, France, May 16-21 2010 (see the Congress website http://www.eccm2010.org/ for more information).
During this conference, we are organizing a Minisymposium entitled:
Fracture and Contact Mechanics for Interface Problems
Hi all,
I am currently working on mooney-rivlin materials. I wonder if someone have tried to compute GI, GII and GIII with the EDI because I don't understand how to compute WIII with mooney-rivlin.
Thanks a lot

Sir,
Iam pursuing my PhD in Fracture mechanics. The thing is I analysed a crack problem with straight crack front and subjected to mode I loading using ansys i.e Three point bending. I was able to get the result for SIF I (KI) in ansys. I took the local coordinate system at the crack tip using three nodes.
I was wondering what are the advantages of damage mechanics and fracture mechanics over each other? Specially in order to model the delamination phenomenon.
Hi!
Can anyone give me some tips within strain based fracture mechanics. My problem is predicting the fatigue life of a gusset speciemen, using strain based FM. I have read some litterature, but have problems on understanding the order of calculating, and methods of solving the equations. If anyone could help me understanding, I would be greatful.
Thanks,
Sean Angus
Hi!
I`m new to this webpage, and hope for some good answers for use in my masters degree within fatigue. Currently I`m working on calculating the total life of a gusset specimen using strain based fracture mecahnics. I`ve read som articles on the topic, but have some difficulties on understanding the calculations itself. I`m using Excel in the calculations. If anyone has an excel-sheet, or other ways of helping me, I would hihgly appreciate it.
Thanks, Sean Angus
