Postodoctoral position in multiphase flow in porous media, University of Texas at Austin

Submitted by masha on

The postdoctoral researcher will develop three-dimensional, network-like
models for fluid displacement in low permeability porous media. Such
porous materials involve multiple relevant length scales (e.g. micro-fractures
connected to the adjacent matrix) and models to date are not representative.

This research-only position will be supervised by Drs. Maša
Prodanović and Steven L. Bryant from Department of Petroleum and Geosystems Engineering, University of Texas at Austin.

Beam on elastic foundation

Submitted by parisa on

Dear All,

I am wondering that is there any closed form solution for beam on elastic foundation in case which we have got two stiffness for the springs namely (axial and shear stiffness). The axial force are born because of the some loading conditions in the support.Would you please help me about this?

Thank you,

Parisa

Post necking behavior (Steel)

Submitted by PKS on

I am simulating the tensile test of steel specimen to confirm that
resulting force displacement data matches with experiment. Since the
true stress true strain formulas are not valid beyond necking i have to
rely on actual neck measurements of flat sheet geometry. I have
identified swifts parameter also to use in the material model but some
how i am unable to match my results beyond necking. Any suggestions??

Strain stiffening induced by molecular motors in active crosslinked biopolymer networks

Submitted by Peng Chen on

We have studied the elastic response of actin networks with both compliant and rigid crosslinks by modeling molecular motors as force dipoles. Our finite element simulations show that for compliant crosslinkers such as filamin A, the network can be stiffened by two orders of magnitude while stiffening achieved with incompliant linkers such as scruin is significantly smaller, typically a factor of two, in excellent agreement with recent experiments.

Had somebody implemented the MMA or GCMMA algorithm (Svanberg) in the 99 lines Topology Optimization Matlab code(Sigmund)?

Submitted by felipecardenas on

Hello everybody,

 I need some help. I have a lot of problems trying to implement the MMA or GCMMA optimizer in the Sigmund's Topology Optimization code (99 lines). Have you ever do that?. Please, is very important for my pregraduate thesis.

Thanks.

Lecture Notes on Composites

Submitted by John R. Willis on

In addition to the notes on stability that I've already posted, I have a set on Composites, which also originated from a lecture course that I gave in Ecole Polytechnique, around 2002. In the hope that they may be of interest at least to someone, here they are! Please do remember that they are just notes and may not be error-free.

resonant behaviour of damped beam

Submitted by laxmaneagertolearn on

 hi

i have a problem in finding the quality factor of cantilever beam (one end is fixed and other end is free ) vibrating in air /other medium? how the qualtiy factor expression for beam is calculated? whether all these expressions applicable to micro and nano cantilevers.

please explain me.

i am new to this area. i read books on vibrations of beam. i didnt get anything

please mention steps for finding quality factor of cantilever beam in air medium(damped system)
