Max Davis I have just recognized you with your name. It is so kind of you the help and sharing your distinguished experiences here. Thanks a lot. I am a Ph.D. student in my last year(Civil/Monash). Hope will be a chance to meet you in person in the near future may be a conference. Now, I'm so...

Blakmax, That's sound great! I will contact them soon and will come back to you for the update. Also, I found his email on RMIT as Adjunct Professor. Link Thanks&Regards

Blakmax, Thank you for following up I agree with you, it would be much helpful if there is a way that the forum members can contact each other, but that unfortunate for now. I will give it try to contact the DSTG. Hopefully being a PhD-student would sound reasonable reason that they provide me...

Blakmax, Thank you so much for your comments & kind offer to help. The nomenclature might be one reason but in the paper, I am working on ((1), more detailed in (2)), it seems no issue with (thickness&load nomenclature)but still there few nomenclator issues in some parts of the paper. So this...

Dave442 Thank you for the helpful comment

Dave442 Thanks for your comments will be appreciated if you have time to follow up with these questions Would you recommend parameter manage for 3D modeling --cracked plate? ..is it practical to adopt? Can control the partition (keep it same) as well as the mesh size/pattern... Do you still...

G'day all, What is the common practice among finite element users when you have to build a number of models of similar geometry but with one changing parameter. For example; Modeling specimen with varying crack length. DO I have to rebuild all the model (geometry, partition, meshing, analysis)...

G'day All I hope some of you in this forum has the knowledge of the work of Wang&Rose. My question is regarding the article 'A crack bridging model for bonded plates subjected to tension and bending'by Wang&Rose 1998. Wand&Rose presented two methods for estimating the stress intensity factor...

LiftDivergence Thanks for your comment Yes, This model for a metal bonded with a composite patch. in Wang&Rose 1998 paper, they presented an example for a cracked aluminum component reinforced with boron/epoxy patches. I already went through most of the papers that cited the abovementioned...

G'day All I expect & hope some of you in this forum has the knowledge of the work of Wang&Rose. My question is regarding the article 'A crack bridging model for bonded plates subjected to tension and bending'by Wang&Rose 1998. Wand&Rose presented two methods for estimating the stress intensity...

Thanks, rb1975 I agree with you regarding plasticity effect, and I had a look at few FEA based fatigue software that deals with such problems. My question is if I assumed crack initiation size from a notch of different orientations is the same, provided that the notch radius, loading level...

Thanks, rb1957 for following up This is the challenge, no information about the crack initiation- has not been monitored in tests! You have to predict the total fatigue life (knowing the test data, can help in checking the accuracy for the assumption). also, as you state there is obvious...

EdStainless, rb1975 Thank you for your comments. I should clarify that my question is about the crack initiation stage. no propagation yet. I like the way rb1975 put it: when the crack-like become crack?. Therefore, as you know the fracture parameter here the plastic strain/metal at this stage...

G'day all, There are different definitions for crack initiation size in the literature. I run into N.E. Dowling papers (and his book) who went through this topic However for the same material, and the same notch size (radius of curvature), Does the crack initiation size changes under (a)...

Hi LiftDivergence I am working to extend the procedure adopted (complex stress function) in the paper of Woo et al 1989 to the case of a plate with smaller hole R to plate width (R/w=0.1) Then the driven K value will cover a wider range like a/W from 0.1 to 0.9. The series equations are so...

Thank you so much LiftDivergence for your help and the paper. It is really interesting and very helpful paper. Unfortunately the presented results were limited for the case presented, i.e.; the hole is 0.25 of the plate width. similarly the range of the crack length/hole radius was less than...

Thanks LiftDivergence for your response The case in my attached is not there. if you see that the case is exactly (hole-with-symmetric cracks) rotated in different angles. so the the slant crack axis is passing through the centre of hole. it is different form slant crack at the tip of hole. Thanks

Thank you rb1957, and LiftDivergence for your valuable comments and generosity with your time to response and help! so much appreciated rb1957 1- Yes 2- Thanks to bringing this important point I already forgot. it stated somewhere that the 2nd normal stress in this case only has effect on...

Thanks rb1957 for your response To clarify my question, please see the attached shows different simulate First, it is Known that we can simulate/approximate case A in Case B. But is Case C (bi-axial loading +straight crack = uni-axial load+inclined crack)an approximate to case A?? is the...

Hi for plate with slant crack loaded uni-axially, If we want to simplified the case by transforming the axis of loading along the axis of the crack and re-modelling the case as plate with a straight crack under tension(remote Stress*sing(angle)^2), and shear (remote stress*sing(angle)*cos(angle)...
