hiii

i m, arun sahu student of IIT kharagpur.my mtech thesis is effect of dynamic loading on slope stability analysis in open cast mines.i hav startted my work using software ABAQUS.can i give velocity as input in abaqus?

and here i just want to give trapezoidal form of load up to 2 sec.so plz help me in these ...............

 

Capturing wetting angles in transient simulations of fluids

Dear all,
I'm trying to simulate the transient behavior of a fluid and I'm finding it very difficult to capture the wetting angle.
To begin with, I only considering the idealized case.

The common approach is to apply the pressure load
p = 2 H γ
where p is the pressure (normal traction) on the surface, H is the Gaussian curvature of the surface, and γ is the surface energy
This load will of course always yield the same equilibrium shape for a viscous fluid, regardless of the value of γ.

Now, comparing with Young's relation, where one obtains a balance containing surface energies for every interface.

Hello

I do my thesis on bearing capacity of foundations near slopes, I use mohr coulomb plasticity with el asticity

but I cant understand what should I do and why my result is dependent on the mesh size and why when I refine elements near

foundation the bearing capacity of the foundation becomes smaller please help me how can I do this thesis

The Research Center for Mechanics of Solids, Structures and Materials at
the University of Texas at Austin invites applications for an open
position as Post-doctoral Fellow. The specific project involves collaboration with the University of Texas MD Anderson Cancer Center in Houston and requires the Fellow to work at both institutions.  The work involves experimental characterization of tissues and surgical remodeling, and development of computational modeling of surgical reconstruction. While specific background in Biomechanics is not necessary, candidates should have a

Prestressed beam - abaqus

Submitted by eng.sara on

Hi,

 I am modelling a prestressed RC beam with abaqus. For the beam I am using the C3D8 element and for the reinforcement and strands the BEAM element and I am using the EMBEDDED command to simulate the contact between the steel and the concrete.

I am trying to simulate the prestressed with the prestressed hold command, but I am not having success because I am not writting the correctly code.

Can someone help me and tell me how I can do this correctly? What should I write? Where can I see that?

 Best regards,

Sara
