Dislocations 2008 International Conference

Submitted by Cai Wei on

We are pleased to announce Dislocations 2008, an international conference on the fundamentals of plastic deformation and other physical phenomena where the dislocations play pivotal roles.  The conference will take place on October 13-17, 2008 at the Gold Coast Hotel, Hong Kong, China.  More information about the Dislocations 2008 conference can be found at the following web site:

Do I really belong here?

Submitted by Timm A Vanderelli on

Greetings iMechanicans

I've been struggling with a optics project for almost 3 years. I say struggle because my lack of a formal physics education leaves an accurate hypothesis out of my reach. I understand solid-state physics, as well as electromagnetic wave theory from my 40+ years of experience and research in these fields.

I hope to spark the mind(s) of anyone who could possibly explain an optomagnetic anomaly that results from this simple Superparamagnetic event that I've created.

Should I leave and try to find the answer elsewhere?

Need help: Relation between polymer end-to-end distance and mechanical properties

Submitted by ashfaqadnan on

Hi,

I found in polymer books and some literatures that mechanical properties of polymer improve with the increase of their radius of gyration or end-to-end distance for a fixed molecular weight. I, however, could not find any experimental evidence or any physical explanation. 

It will be a great help to me if anyone refer me some literatures that explains the connection between these two parameters.

 Thanks,

Ashfaq Adnan

Interaction Integral Method for bimaterial interface

Submitted by Dhaneshwar Mishra on

I am Dhaneshwar Mishra, currently a PhD student at Ajou University, South Korea. I am working in the area of Bimaterial Fracture. Currently i am trying to calculate Stress Intensity factor of cracked bimaterial plate. I wanted to use Interaction Integral Method to seperate Complex stress intensity factor.

Will some one please through light on use of interaction Integral Method used for cracked bimaterial interfaces.

Hope to receive early suggestions.

 

Thank you.

 

With regards
