Necking Analysis of Strain Softening Materials ...
Hi all.
I'm studying the high temperature viscoplastic behavior of titanium alloys. It is well known that at high temperature range, deformation induced dynamic recrystallization (DRX) causes dramatically strain softening. Such strain softening behavior is also treated as plastic instable according to literatures.

Starting with a solid mechanics background, I have been recently interested in fluid-structure interactions for applications in biomechanics of soft-tissues; and thought that the iMechanica Journal Club forum would be a good opportunity to share my personal experience and start a discussion on this challenging inter-disciplinary subject.

Unsolicited proposals on Dynamical Systems
The Dynamical Systems program in the Directorate of Engineering and the Applied Mathematics Program in the directorate of Mathematical and Physical Sciences Sciences, of the National Science Foundation, have just published a joint "Dear Colleague Letter", expressing interest in special topics in Dynamical Systems. The letter encourages unsolicited proposals on the following topics:
hydrostatic loading on inside and outside of ship shell plate
as you can see in attached, my model has been included too many small area, on the other hand hydrostatic and hydro dynamic pressure are gradient loads, so how we can apply these loads on inside and outside of shell plates as gradient loads?
Exact relations in the micromechanics of composites
There are several exact relations from the theory of composites that can be used to determine whether a new numerical or analytical approach gives reasonable answers. Here's a paper on some exact relations that I wrote up a long time ago and just recently posted on Scribd.
