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

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,

Subject to a voltage, a dielectric elastomer can deform substantially, making it a desirable material for actuators. Designing such an actuator, however, has been challenging due to nonlinear equations of state, as well as multiple modes of failure, parameters of design, and measures of performance. This paper explores these issues, using a spring-roll actuator as an example.
