Hi Dear IMechanica User
I have faced up a problem during micro-scale cutting using abrasives. I am trying to model this process using Abaqus/explicit and with remeshing module. but currently there doesnt exist any remeshing technique in abaqus/explicit. Could you please suggest the way for doing this simulation by using remeshing technique in Abaqus/explicit. Abaqus/standard is not helpfull to model cutting simulation. this is because i am using Abaqus/explicit by the way.
I am awaiting your valuable suggestions and helpfull informations.
My name is Jinqiang Li. Now I am a study student in Hokkaido University. Next April(2010) I will be a first year Ph.D student (Graduate School of Engineering, Division of Human Mechanical Systems and Design, Research Group of Micromechanical Systems). I got my Master degree in General Mechanics and Mechanics Foundations from Harbin Institute of Technology. I know that most of you are very learned man in mechanics, I hope I can enrich my faculty and knowledge from your wisdom and insights.
Hello everyone!
I'm interested in branching of Mode II propagating crack, mostly in high Cr steels, but any info may be useful and interesting. Does it tend to branch? What are the criteria? Velocity? Angle of branching?
Thanks,
Marina
Dear All:
I have a structural problem which deals with "Buckling" analysis of a boom with a rectangular cross-sectional area
and 0.25 in. thickness.
Can I use brick element (8 nodes) instead of shell element to simulate buckling of this type of structure?
Thank you for your insight.
David.

HI,
i am looking into strain field measurement for coupon tension tests for the purpose of correlation to fea results . a collegue told me that there is an open source project
which calculates strain field from camera images. does anybody know something about it?
Cheers,
schuffe
