Hello everybody

                     could anyone please tell me how to improve the convergence when using XFEM in Abaqus 6.10. I have tried small min increment 2.5e-16 and a total no of increments 1e9. Also, I have changed the control parameters to discontinuous analysis Io=8, IR=10, and IA=20 but actually I was not able to persuade XFEM to finalise the job.

 Please help as all my life is waiting at that point.

Hello,

 Am working on post tension prestressed concrete with Abaqus,

1-  I would like to know where to find the "initial conditions option and prestress hold" in which module??

2- Rebar option: as per the Help, it is mentioned that i can define a rebar as individual element not as rebar layer in a shell/membrane element. but also couldn't be able to find how and in which module?

Any suggestions?

Wating for a quick feedback

thanks

Dear All



I am working on Abaqus simulation for thermo-visco-plasticity, especially on necking problem in circular bar.

I need the plastic strain data to add in the material properties table of Abaqus.

And, any help in this regard would be appreciated.



Thanks

I'm trying to plot the stress-strain curve described by the Johnson-Cook strength (and eventually damage) models. The strength model is defined as:

σ=[A+Bεⁿ][1+C ln(ε_dot*)][1-T*^m]

where A, B, C, n, and m are material constants, ε_dot* is the non-dimensionalized strain rate, and T* is the homologous temperature where T*=(T-T0)/(Tmelt-T0)

Hi,

I have run a job through command window in Abaqus. I would like to display the Dload in the .odb file , but I couldn't figure out how to do that yet. I really appriciate if anybody helps me about that?

Thanks
