Failure mechanics is comprised of the failure theory for homogeneous and isotropic materials along with all of its implications and applications. The present failure theory is found to have an intimate connection with elasticity behavior even though plasticity may also transpire. This becomes apparent and useful when the classical theory of elasticity is renormalized to give a simpler and more transparent (but still exact) formalism. The connection or coordination between elasticity and failure then explicitly occurs through the use of the renormalized Poisson's ratio to characterize the ductility of failure. With this unification of failure theory and elasticity theory, failure mechanics can be extended to explain other anomalous aspects of mechanical behavior and prepare it for applications.

The ASME website says that I have to pay US $25 for the paper, and presumably $25 each for several of the references cited.  Assuming that 10 of the references are needed to understand the contents of the paper, the cost of reading the paper is US $225.  It is not obvious from the abstract that the work is important enough that we should pay this amount to read the paper.

Indeed one can ask the author and that is what I do in most cases.  However, I am not sure that the author owns the copyright to the paper and whether he has the right to distribute free copies to the general public.  The last thing I was is an author to be sued because of their willingness to help others. 

The matter boils down to one of principle.  ASME (and other publishers) can afford to sell electronic versions of its papers for a much lower cost but they choose not to.  The question is: should we continue to support the current system and make our publications available only to a small elite (and for a limited period of time)? 

We can find out about papers published in ASME from their web site and from their journal RSS feeds.  How does avertising on iMechanica help the mechanics community unless the paper is made freely available on this site?
