PhD (4 years) on micromechanical testing and interface characterization of composites

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.

Open Master's or PhD position for Fall 2023 on experimental mechanics

One MS or PhD student is sought to fill an opening in the Gross Materials Lab (group website: andrewjgross.com) at the University of South Carolina. This research is focused on conducting novel mechanical experiments with advanced metrology. This research is primarily experimental and will integrate with the work of a postdoc working on computational methods to distill the multitudes of data into information that practicing engineers rely on. Students must have prior hands on experience to be considered (any prior experience is OK, whether it be in a lab, garage, shop, etc.).

Postdoctoral and PhD positions in synthesis and in situ micromechanics of nanocrystalline alloys

Applications are invited for postdoctoral and doctoral (PhD) research positions in the Department of Mechanical Engineering at the University of Vermont (USA) and are available immediately. The successful researchers will work in the Sansoz Laboratory for Nanostructured Materials Science and Engineering on funded projects to study grain boundary segregation and strain localization mechanisms in a range of nanocrystalline metallic alloys. These positions are focused on experimental nanocrystalline film synthesis and in-situ tensile SEM characterization.

Exciting new vacancy - MatchID US subsidiary

Given our substantial growth over the past few years, MatchID deems the time right to expand our horizon and evolve from a spin-off towards a truly international scaled-up company. To that purpose we will establish a US subsidiary that will not only give us a local physical presence, but also help convey more directly our philosophy to potential customers for a widespread range of applications and market verticals.

Industrial PhD studentship available (EU/UK students only), University of Southampton, UK

A PhD studentship is available at the University of Southampton as part of a collaboration with MatchID NV. It consists at exploring new heterogeneous test configurations for composites and elastomers, based on Digital Image Correlation (DIC) and the Virtual Fields Method (VFM). The overarching goal is to propose new standard tests relying on heterogeneous states of strain and stress for cheaper and more robust material testing.

Design of a porous material with isotropic negative Poisson's ratio

This paper proposes the design of a two-dimensional porous solid with omnidirectional negative Poisson's ratio. The hexagonal periodic distribution of the pores makes the effective behavior isotropic. Both experimental tests and numerical simulations have been performed to determine the effective properties of the porous solid. A parametric study on the effect of the geometrical microstructural parameters is also presented. This auxetic structure is easy to fabricate and can be very useful in several engineering applications.

Optical microscope for three-dimensional surface displacement and shape measurements at the microscale

We report a novel optical microscope for full-field, noncontact measurements of three-dimensional (3D) surface deformation and topography at the microscale. The microscope system is based on a seamless integration of the diffraction-assisted image correlation (DAIC) method with fluorescent microscopy. We experimentally demonstrate the microscope’s capability for 3D measurements with submicrometer spatial resolution and subpixel measurement accuracy.

PhD Studentship: In-situ quantification of interphase stress during martensitic transformations, Open University, UK

Fully funded PhD studentship at The Open Univeristy campus, Milton Keynes, UK. The aim of this project is to optimise experimental techniques such as digital image correlation (DIC) and focused ion beam (FIB) hole drilling to investigate the micro scale stresses and strains occurring during martensitic transformations. The techniques will be applied to a range of materials from simple steels to complex shape memory alloys. There will also be scope within the project to study martensitic alloys using central facilities such as the ILL, ESRF and Diamond light source.

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.

Subset Splitting Digital Image Correlation (SSDIC)

Following our recent article on this new method, we are making our Matlab routines available. The package contains standard DIC, SSDIC, plus a few extras. More info here

“Subset Splitting Digital Image Correlation” (SSDIC) is based on DIC, but in addition SSDIC can capture displacement discontinuities near shear bands or cracks, where standard DIC fails.

Multi-Scale Digital Image Correlation and Tracking with MATLAB

C. Eberl, D. S. Gianola, R. J. Thompson (in alphabetic order)

 

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.
