POSTDOCTORAL RESEARCH SCIENTIST – Mechanics and Fracture of ice sheets

These notes were initially written when I taught fracture mechanics in spring 2010.  The title of the notes was then "toughness".  In revising the notes for the class in 2014, I have changed the title of the notes to "Linear elastic fracture mechanics".

You can access all notes for the course on fracture mechanics. 

Dear all: 

Dear. Collegue

2nd International Conference of Engineering Against Fracture (ICEAF II), Mykonos, Greece, 22-24 June 2011

Dear Colleague:

The Society of the Engineering Science is sponsoring the 47th Annual Technical Meeting (SES2010) on October 4-6, 2010 at Iowa State University in Ames, IA. The meeting is held on biannual basis as a standalone meeting to foster and promote the exchange of ideas and information among the various disciplines of engineering and the fields of physics, chemistry, mathematics, bioengineering and related scientific and engineering fields.

Mechanics is the paradise of

the mathematical sciences

because by
means of it

one comes to the fruits

of mathematics.

In this paper we extend the classical method of lattice dynamics to defective crystals with partial symmetries. We start by a nominal defect configuration and first relax it statically. Having the static equilibrium configuration, we use a quasiharmonic lattice dynamics approach to approximate the free energy. Finally, the defect structure at a finite temperature is obtained by minimizing the approximate Helmholtz free energy. For higher temperatures we take the relaxed configuration at a lower temperature as the reference configuration.

Hi all,

I am starting to my phd project focusing on developing new interatomic potentials.

Would you please help introduce some of current research trends(such as review paper, existed potentials etc) on this field.

Thanks.

The Integrated Structure Technical Committee in the Applied Mechanics Division of ASME invite you to submit an abstract to the Symposium on Mechanics of Integrated Structures and Hybrid Materials in Advanced Technologies at the 2010 ASME International Mechanical Engineering Congress & Exposition (IMECE).
