Hi everyone,
I want to model friction in crack surface and investigate the effect of it in my modeling. I want to do it in abaqus.
thanks.
I am performing a nonlinear post buckling using Riks method. I went through different tutorials for the same. I happen to see that an *IMPERFECTION is introduced while performing the non linear buckling analysis.Why is it done? How does/will the model react differently if the Imperfection is no introduced?
I wish to plot the graph of load v/s displacement for 1,2,3,4...10 times the critical buckling load during the post buckling analysis (Riks method). How do I do that?
Hi every one,
I need to modeling a thermal analysis of a microstructure of steel or other alloy by FEM or XFEM. so i need some metallurgical data for phase transformation.for example at which temperature or time martensit converts to austenit or etc. I also need how I can model this microstructure in abaqus that has change in boundries due to phase transformation. i appreciate if someone help me.
thanks
Modelling of Dislocation-Microstructure Interaction at a Short Crack Tip
This project aims to model dislocation-microstructure interaction at a crack tip and associated short crack growth for nickel alloys.

Please drop your CV to lihua [at] ntu.edu.sg (lihua[at]ntu[dot]edu[dot]sg), if you are interested in it. Thank you.
could someone tell me some equation to get the critical stress for delamination in multilayers?
Thanks,
Are m and C in the paris law equation dependant on the material property or geometry?
For example if using the same material with different thickness, do the C and m values change? For clarity assume centre notched plates, with different plate thicknesses but same material (steel or aluminium).
I appreciate your time.
