Dear Mechanicians,

Dear all,

 I am trying to simulate the local stresses and strains in a dual-phase metal and total behaviour of this metal in ABAQUS-6.7, what I have is the optical microscopic pictures of phases inside the metal which has been measured by some help of physicists. The pictures are of extension file name .tif ad .gif. How could I construct a mesh in Abaqus with this colorful pictures ?

Any help is appreciated much. Thanks in advance

Regards

Dear All,

 I am trying to get the paper as the following, but I failed by all the ways, Could someone be kind enough to send me ?!!!

Panontin, T. L. and M. R. Hill (1996). "The effect of residual stresses
on brittle and ductile fracture initiation predicted by micromechanical models."
International Journal of Fracture 82: pp. 317-333.

 Thank in advance,

Dear Mechanicians,

 Recently I have seen many researches on the crystal plasticity, Could someone tell me some basic difference between classic plasticity and crystal plasticity ?! and what is the crystal plasticity theory for ? 

Thank you very much

Dear mechanicians,

I am trying to get the information, orientation on the modelling of thermomechanical treatment of steel (Duplex stainless steel), since during the treatment process, both tensile stress and temperature (150oC-300oC) are applied for a time interval and as a result the original phases of material change to new phases. After the thermomechanical treatment, we get the new materials with different mechanical properties such as elastic limit, yield stress, ductility....
