education

Hi,



I'm an Engineer and a Ph.D. student in Applied Maths, working in the field of Nonlinear Finite Elements for Elasticity. I often think about my future career since, by now, I have a strong experience with coding FE in C++/Matlab/Mathematica, but no clue whatsoever about commercial black-box softwares for FEA. I'm worried about this, since most of the job vacancies from the industry (I'm not interested in pursuing the Academic career) seem to require only experience with a specific software and application, and not to directly code FE.

Hi,

I am doing some test on the fracture toughness.

I am wondering if in Linear Elastic Fracture Mechanics, Fracture toughness of the material is equal to fracture energy or not?

Can anybody send me an naswer,

Thank you,

Manooir

dear Friend



I am comparing italian universities with Russian ones with US and with Cuban ones. Then I need some figures.



I have been able for example to find that there are about 50% of students-workers in Russia, what about US?

I mean full time workers, not just part time.



But I need to know more about these questions:-

1) how did the number of students in the last 10 years vary?  Increased?

2) how many students are doing economics or management - related subjects?

I’ve just come back from a Winter School on Dielectric Elastomer Transducers, held at Monte Verità, Ascona, Switzerland, 10-16 January 2010.  Lectures were given by various people, covering the theory of electromechanical interaction, design of devices, development of materials, and technologies of manufacturing.  I was asked to give three lectures on the theory.  I attach the slides of my lectures.

It is well known thatdislocations in FCC metals are composed of partial dislocations separated bystacking faults.  When consideringthe reactions of dislocations with each other, such as in DD simulations, it is necessary to determine therelative positions of the partials in order to correctly describe theconfigurations that are created in the reactions.  Here we describe a geometric method for correctly determiningthe relative positions of the partials. The results we obtain can also be found by applying an axiom, or rule,given in the book by Hirth and Lothe. At the end
