Questions about dislocation souce

Submitted by Xu Zhang on
research

As our body, we birth, grow up and dead? Wil the dislocation souce be the same process, if it’s so, what’s the detail process.

(1):the birth of dislocation source

There are many dislocation multiplication mechanism, such Frank-Read source, cross-slip mechanism, L-source. So the questions is that when will these mechanism become active, will the stress be the only criterion? IF so ,what determine the critical stress? Will this critical stress change with the deformation, how is this change?

(2):the evolution of dislocation source

Citation analysis? it is an old story!

citation
Scientometrics

I started my research on citation system with a very positve attitude about that. I have read many of scientometrics papers, but now I am completely disappoined! In the report by the International Mathematical Union (IMU) (attached) about citation statistics. I found an interesting sentence! Citation should not be used for evaluation of different papers in two different disciplines. How about different papers from two different sub-disciplines? and even two different  sub-sub-disciplines? and so on!

stepTime vs. totalTime in VUMAT

Hi

I’m trying to develop a VUMat routine so I’ve already
started to learn its features. I recently got this problem that what exactly
the variable stepTime means! I created a model with 3 steps including the initial
step and I coded my routine somehow that when the stepTime is equal to 0 it
prints something into a file. Surprisingly only once in whole analysis the
stepTime would be 0 and that’s exactly at the beginning of the analysis when
totalTime is in fact 0. Could anyone please explain why this happens?

 

Thanks

Memories of IT. Part 1

Submitted by Zhigang Suo on

I finally got around to read Does IT Matter, the 2004 book by Nicholas Carr.  He used the phrase IT (Information Technology) in "its commonly understood sense today, as denoting all the technology, both hardware and software, used to store, process, and transport information in digital form."  He explained, "The meaning of "IT" does not encompass the information that flows through the technology or the talent of the people using the technology."

Hi all,

It is very good to see postdoc jobs posted in imechanica .I want to apply for postdoc position in solid mechanics ,however, i have never written a postdoc research proposal.I dont know how it is different from statement of purpose that is required for a graduate research. 

I tried but could not find any sample postdoc research proposal on internet.

I would greatly help if anyone can send me his/her actual or sample postdoc research proposal 

Thanks and Regards,

Sonia Chopra
