We are looking for a PhD student for a research project on microscale mechanical characterization of fiber reinforced polymer composites using in-situ microscopic techniques. Much more fundamental insights and measurements at the micro-scale are necessary to enable fully predictive multi-scale modelling and faster adaptation of composites. Therefore, we have developed advanced micromechanical test methods for fibre reinforced polymer composites based on in-situ optical and electron microscopy during loading.

I was wondering if anyone knows of an analytic Solution for KI and/or KII in tubes.

I´ve seen an infinite number of equations, shape functions, FEM simulations, standards, etc. But one closed solution for tubes?, an analog to Williams series but for cilindirical surfaces?

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.

With this contribution we would like to point to a free MATLAB tool which uses digital image correlation and tracking techniques to measure strain from a series of digital images. The code can be found on the ‘MATLAB central file exchange’ as well as the documentation, example images and some slides. We use the code on a daily basis for micro- and nanoscale measurements and present it here to be used and further developed by the community. Since it was posted at the end of september the code is now ranked place one or two in google and has been downloaded about 1000 times.
