Matlab-based Digital Image and Volume Correlation Simulators

Hi,
I just posted a Matlab-GUI easy-to-use DIC and DVC simulator tool on our website (franck.engin.brown.edu) for download for anyone that works with DIC or DVC. The purpose of these simulators is to simulate deformation fields based on a user provided image (2D) or volume (3D), and evaluate the correlation results with the analytical solutions to provide quantitative feedback on the "goodness" of the provided images for DIC or DVC purposes.
Feel free to use them for research, teaching, etc. We welcome any suggestions for improvements, etc.

Dear Colleagues,

Following the last successful events in the past years, the next ESAFORM
Conference on Material Forming (ESAFORM 2013) will represent the 16th
edition of one of the most important and well-established international
research meetings on the material forming field. The conference will be held
at the University of Aveiro, Portugal, from 22 to 24 of April, 2013.

I wender about the limitation of the Navier methode for the solution of the probleme of plate " Why is vailable only for simply supported plates " for wiche raison " mathimathicaly or another thing.........?

thanks 

selected papers on fracture in layered materials

Submitted by kilading on
education

Dear All,

 Currently I am working on the fracture property in layered material and I am focusing on the situation when crack is perpendicular to 

interface. I have read the paper by Dr. Hutchinson and Dr. Suo. If you know any paper that is focusing on the crack perpendicular to the 

interface, please tell me.

 

Thanks and Regards,

Difficulties in indexing monoclinic crystalline materials by wide angle X-ray diffraction

X-ray diffraction
monoclinic

For monoclinic polycrystalline materials, how can we uniquely index the X-ray diffraction spectrum so that we can calculate the accurate lattice parameters a, b, c and beta? Due to the fact that there are four unknown variables coupled to determine d-spacings, we can not easily read out the lattice parameters until enough diffraction peaks positions are obtained correctly. This leads to two questions

1. How do we get the full diffraction peaks from a monoclinic polycrystalline sample if it is partially textured?

Weyl Geometry and the Nonlinear Mechanics of Distributed Point Defects

Submitted by arash_yavari on
research

In this paper we obtain the residual stress field of a nonlinear elastic solid with a spherically-symmetric distribution of point defects. To our best knowledge, this is the first nonlinear solution for point defects since the linear solution of Love in the 1920s.
