oh, i found it already!, just calculate the path integration! I was confused because i made error in computing integration so the result was different with my teacher. Now everything's done!

Sozi, I've just found this is about thermal conductivity of a nanowire ^^. And I have to use Matlab with the given eqs. to calculate the thermal conductivity k, but there is still some variables/parameters which I've not understand: in the eq.(1): where can I find the Kbulk and Phonon...

Hi all, I am new to matlab, and I have a question (in page 2 and 3 of attached file). As I understand, i have some equations to calculate the thermal conductivity of the pipe-like solid, and I have to use Matlab to make a program to do it. But i don't know where to start? It may be easy...

I forgot the arrow for path (1) and (2): Path (1): O => B => A Path (2): O => C => A Path (3): O => A

Hi there, My teacher gave me a homework, but this Theory of Plasticity is new and difficult to me. He has calculated the strain according to path (1), now I have to do with the path (2) and (3). This is what he did with path (1): ε11=∫(1/E)dσ11 +...

Thanks very much, i have submitted my HW he!

(please use the X2 and X2 buttons just above the Reply box ) Sorry, i have not been accustomed to this site

Hi tiny-tim, Thanks for your help. Because I have just started to learned this subject and the author of the book has written like that so I copy original version only :P please see the picture! i have understood something after reading your answer but if you can do it completely, i can...

No, please see the expression again, there is a bracket pair and i symbol at the end: (x1^2 + 2x1*x2^2 + 3x2^2*x3), i I have uploaded the picture of the exercise 16: http://img252.imageshack.us/img252/4437/66167045.png In the same occasion, if you know the meaning of some symbols and eq to...

Homework Statement This exercice is in a Chapter named Introduction to Cartesian tensors. The following is the original question of the exercise: Homework Equations Compute the vector: (x1^2 + 2x1*x2^2 + 3x2^2*x3), i The Attempt at a Solution Plz help me, i don't understand what...
