Does anyone know of a good source for free science and engineering illustrations? I'm particularly interested in crystallography, crystal defects/dislocations, and mechanical properties illustrations.

Thanks 

Hi, everyone:

    I'm recently very interested in computational nolinearity. Would you like recommend some monographs on the computation nonlinearity so that i can have a better understanding of the mechanism of ABAQUS.

    Thanks

 Dear all:

    I recently find an example in ABAQUS documentation cannont convergence.

    The parametres related with the iteration of the Risk method is 

I recent read the book of Prof. J. Tinsley Oden "A short course on nonlinear continuum mechanics"

 http://users.ices.utexas.edu/~arbogast/cam397/oden0908.pdf

 which declares that reference configuration is an open, bounded, connected subset  of R3 with a smooth boundary (in Page 1).

It is strange to me beacause that means we cannot consider the boundary of the deformable bodies in its following discussion.

does anybody have  the abaqus seminar pdf ''modelling heat transfer and thermal-stress analysis with abaqus'' ???

 perhaps an older version...i d like learn it, hope u guys can help me, thank u very much.

if u have the pdf file, please give a freelink with dropbox or sth alke, or send me direct to zsc13810288137 [at] hotmail.com

hi i am new to abaqus software.  i am doing research on failure analysis of composite material.  i want to model the workpiece and machine by a tool.  any one can please help me if you have any tutorial to model this explicit analysis.  i want to analyse the chip also.

please send the help link to stkrajan [at] gmail.com (stkrajan[at]gmail[dot]com)

thankyou

with regards

Saber El Arem (node/14053 ) wanted to know how a fractal surface mesh could be created.

I've had to do that in the past.  What I did was to use Arjun Viswanathan's 1999 Matlab snippet on creating a plasma fractal and write a wrapper around it to create an output file that could be read by the then available version of Abaqus.

I've attached a couple of Matlab files that should be able to do the job.   The .txt extensions are needed because iMechanica does not accept files with .m extensions.
