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

Anil

Hi guys

I want to simulate a problem with abaqus,but during runing of my project,percent of process not increas for axample when i change mesh sizes to biger runing go up to 50 % and when i change mesh sizes to smaller than the previos size,it occure again but in 25%

is there any one that know about this problem,i'm trying to solve it for 2weeks but i cann't.

I'm waiting for your suggestions...
