Two surfaces are ”sticky” if breaking their mutual contact requires a finite tensile force. At low fractal dimensions D, there is consensus stickiness does not depend on the upper truncation frequency of roughness spectrum (or ”magnification”). As debate is still open for the case at high D, we exploit BAM theory of Ciavarella and Persson-Tosatti theory, to derive criteria for all fractal dimensions. For high D, we show that stickiness is more influenced by short wavelength roughness with respect to the low D case.

We are seeking two outstanding postdoctoral candidates to complement the expertise in computational mechanics at the Department of Engineering Mechanics at KTH Royal Institute of Technology, Stcokholm, Sweden.

The research — We use x-ray phase contrast imaging (XPCI) to study deformation and fracture of materials under dynamic loading on microsecond and sub-microsecond time scales. For example, we might like to measure the change in pore size distribution of a granular material such as sandstone under impact loading. Answering this question requires us to address theoretical and computational questions of XPCI image interpretation, and also poses an interesting challenge to the experimentalist.

There is an immediate opening for a post-doctoral scholar in the Hopkins Extreme Materials Institute (http://hemi.jhu.edu) at Johns Hopkins University, working with Prof. K.T. Ramesh (ramesh [at] jhu.edu (ramesh[at]jhu[dot]edu)) and Prof. Todd Hufnagel (hufnagel [at] jhu.edu (hufnagel[at]jhu[dot]edu)).

Dear Colleagues,

Please find our new paper titled "Photochemical-induced phase transitions in photoactive semicrystalline polymers" published in Physical Review E. We used phase field model to investigate photochemical phase transitions in semicrystalline polymers.

Applications are invited for a Postdoctoral Fellow research position in modelling fracturing with thermal-hydro-mechanical (THM) coupling processes at Wuhan University. Code writing ability and strong background in numerical modelling are required. Specific knowledge of TOUGH2 and parallel processing is preferred. Applicants must hold a PhD in Petroleum Engineering, Civil Engineering, Mechanical Engineering, Applied Mathematics, or a related discipline.

We have a number of open permanent positions at Assistant Professor level in the Department of Engineering at Durham University in the UK. We are seeking to fill posts in civil or structural engineering, and in offshore geotechnical engineering, with no restriction on nature of interests, e.g. computational or otherwise.

Dear All,

We cordially invite you to submit a manuscript for consideration and possible publication in the special issue on "Advanced numerical modelling in geotechnical engineering" in Engineering Analysis with Boundary Elements (IF=2.884).

This special issue aims to address following topics:

1. Data-driven simulation with field monitoring or experiments.
