How NOT to use Powerponit! Very instructive and memorable.

   A large quantity of small molecules may migrate into a network of long polymers, causing the network to swell, forming an aggregate known as a polymeric gel.  This paper formulates a theory of the coupled mass transport and large deformation.

Following Andy's recommendation I have been reading Ellis Dill's Continuum Mechanics[1]. In page 75 of the book, we find the
well known result that the constitutive equation for an isotropic hypoelastic
material can be derived from a stored energy function only if

where and are the Lame constants.

The Department of Civil Engineering at North Carolina State University is inviting applications for a possible tenure-track position in the broad area of advanced materials. The solicitation is part of a broader search, with the goal of filling one or more positions in the department; please see the official advertisement at the end of this message. Note that the advertisement does not give any specific details about the desirable properties of the advanced materials applicant. They are summarized below.

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:

It broke in the weekend when I was enjoying the footie on TV with a pack of crisps.

This isn't the first time a tooth filling has broken on me, but this one has got me worried, because I called my dentist today and found out that because he is moving premises, he is not open until the middle of next week.

Dear all,

Infinity asked me for posting more information about one of our papers. It was published in 2006 in Rubber Chemistry and Technology and proposes a comparison and a ranking of 20 different hyperelastic constitutive models for rubber (from the Mooney model (1940) to the micro-sphere model (2004)) in the incompressible case.
