What does a dislocation look like in a spherical geometry, and how does it migrate in such a structure? We report here the counterintuitive motion of the 1/2⟨0001⟩ edge dislocation in carbon onions from the outer surface to the inner core, i.e. from a low pressure surface to a high pressure core, rather than from the core to the surface as expected due to a surface image force. Maybe you can help us to explain this peculiar phenomenon.

I am studying the effect of intermediate microfabric on clay's mechanical behavior. In order to develope the constitutive model for clay considering its microfabric, I want to use fabric tensor. If any good paper or study material on fabric tensor is available then please send me.

Thanks

Hi 

Hi all,

I want to FEA of normal tensile creep test using Abaqus. Can anyone suggest me some notes/books/literature.

Thanks

Hello

I was analyzing pavement subjected to traffic wheel load. I was using the load as cyclic pressure. Suppose an amount of pressure with 200 different time frame. But I am not getting the right result as measured. So, would you please help on applying moving load? How can I assigned that load as moving load? where can I find the step load function? how can I determine the initial increment? is it more realistic to simulate the wheel load as dynamic? how can I do that?

Thanks a lot.

 

 Best regards,

Hi

 I am facing some problems with FRANC3D 3.2 as my getting different errors. Does anyone has the older version of FRANC3D i.e. version 2.6.

Furthermore all the manuals are for older version.

Kindly let me know if anyone has.

Thanks
