Rise in bacon prices a squealing good sign for the economy

Submitted by BradleyI on

There has been a Russian wheat crisis and harvest problems in Europe. This means purchasing a pint of beer in Europe is now going to cost about $ 6.30. But what's worse is that bacon prices are going up. CNBC explains that bacon costs 20 percent more than it did last year. The prices rising is a good thing considering the U.S. economy. Of course you will find some people a little upset by the whole idea of paying more for bacon.

call drop

 I think having Multi Function and multi tasking Mobile Phones r having problem of call drop as compared to other phones having less features the reason being as heat flows from High temperature(Mobile) to low temp(atmosphere) , Infrared radiation creates a barrier to the signal wave and such problem can be rectify by mobile cooling may be done Acoustically.

Post-doctoral Position in Biomechanics at University of Texas

job

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

Calculation of Power law frequency dependence in ABAQUS

Submitted by bugatti87 on

Hi everyone:

Now i am doing a dynamic analysis of a sandwich structure in ABAQUS
,which is consist of viscoelastic (ER) material and elastic ones. I want to
input viscoelastic material parameters by means of Frequency=formula.But
I have only formula of shear modulus(including storage modulus and
loss modulus expressed in frequency domain) about the material
,Real(G)=G',Loss
factor=G'',(G=G'+iG'').So how can i
get the paraments required by Frequency=Formula? Thank you and waiting
for your answer!
