Laguna Beach, CA June 23, 2008 -- Kebaili Corporation a leading California based high-tech company in MEMS and nanotechnology, announced today the release of the KMHP-100 Series, the industry’s first commercially available off-the-shelf MEMS microhotplates for researchers and scientists in innovative chemical sensor research and development applications.

 

Artificially High Read Counts

Submitted by ericmock on

 

There has been some discussion about the low ratio of replies to reads on iMechanica.  While it's nice to think that a lot of people are reading our posts, I wonder how many of those 'reads' are really bots indexing the page.  For example, I posted a blog entry last night around 11:00 and nine hours later it says it has been read 45 times.  A couple of those can be attributed to me but I'm sure 40 real people have not read the post.  Add to this the fact that the post is already showing up in Google.

Effects of grain boundary adhesion and grain size on ductility of thin metal films on polymer substrates

Submitted by Teng Li on

We study the effects of grain boundary adhesion and grain size on the ductility of thin metal films well bonded to polymer substrates, using finite element method. It is shown that the ductility of polymer-supported metal films increases approximately linearly as the grain boundary adhesion increases, and as the grain size decreases. A rule-of-thumb estimate of the ductility of polymer-supported metal films agrees well with the simulation results.

Viscoelastic prarameters setting in ABAQUs

Submitted by h.l.Li on

i'm try to do a dynamic analysis by abaqus and i faced some problems.any help is appreciated.

The structure is a 3 layers plates,a viscoelastic material sandwich between 2 steels.i modeled the 2 steel as sheel 'S8R"and the rubber as contiuum  "c3d20r",rubber is not thin. Now i don't know how to set the parameters requried by the Code.I hove some parameters abuout the viscoelastic material.,includeing shear storage modulus G(f)=exp(-2.69292)*f^(0.6937),and loss factor of the material L(f)=exp(0.60503)*f^(-0.08807), Possion ratio=0.49, where f is frequency in Hz.
