This is the discussion blog for the MSc course "Fundamental Safety Engineering and Risk Management Concepts" lectured at the School of Engineering, University of Aberdeen. This course is a core module for the following Postgraduate Taught Programmes:
Hello everyone,
One of the papers from the 'past' (but still quite actual...I think) and maybe of some interest to various communities.
Abstract:
A system in which one adherend had two types of surface treatment was tested using a wedge test.
Simple polishing and polishing with subsequent sandblasting were the
treatments used, with a distinct straight line, perpendicular to the sample edges,
separating the two. Despite the clear-cut difference in surface treatment, smooth
The Division seeks to employ a Post Doctoral Fellow within the Hydraulic Fracturing research team. The Post Doctoral Fellow will be required to work on a project to develop a new capability in the interpretation of remote sensing data for the purpose of hydraulic fracturing monitoring.

ME/PhD Positions open: Fracture Simulation for Visual Effects
High speed simulations of the fracture of wood, glass, concrete, brick walls, and many other materials are used every day in the visual
effects industry. The project team will develop the next generation of fracture effects technology, bringing visual effects fracturing to the next level through novel computational methods in conjunction with realistic material models for deformation and fracture.
We would like to invite you to attend the
Sixth International Conference on Nonlinear Mechanics, which will be held from
12th to 15th August, 2013 in Shanghai.
The Sixth International Conference on
Nonlinear Mechanics is dedicated to the latest advancements in the science,
technology and applications of nonlinear mechanics.
The conference will provide
a forum for academic researchers, engineers, and students to summarize the
recent achievements and research activities made in this area.
Nanoscale fracture of graphene under coupled in-plane opening and shear
mechanical loading is investigated by extensive molecular dynamics
simulations. Under opening-dominant loading, zigzag edge cracks grow
self-similarly. Otherwise, complex stresses concentrated around
crack-tip can manipulate the direction of crack initiation changing by
30° (or multiples of 30°). Toughness determined by obtained critical
stress intensity factors 2.63–3.38 nN Å−3/2
demonstrates that graphene is intrinsically brittle opposite to its
exceptional high strength at room temperature. Torn zigzag edges are
more energetically and kinetically favorable. Cracking of graphene has
The dielectric constant is an essential electrical parameter to the
achievable voltage-induced deformation of the dielectric
elastomer. This paper primarily focuses on the temperature
dependence of the dielectric constant (within the range of 173 K
to 373 K) for the most widely used acrylic dielectric
elastomer (VHB 4910). First the dielectric constant was investigated
experimentally with the broadband dielectric spectrometer
(BDS). Results showed that the dielectric constant first increased
with temperature up to a peak value and then dropped to a
relative small value. Then by analyzing the fitted curves, the Cole–Cole
dispersion equation was found better to characterize the
rising process before the peak values than the Debye dispersion
At the nanobiophysics laboratory we are looking for a post doc to participate on an experimental work regarding the tuning of fluorescence in nanoparticles under the effect of pressure. We believe that it is the strain rather the pressure that is causing the shift in the emission. We are also investigating this effect using numerical models. While we are looking for an experimentalist urgently we will be looking for a theoretician/numerical guy in a year. All welcome if you have the right attitude and motivation.
I have been asked questions about how the shear modification was introduced to the Gurson model. I was also asked to compare my modification (see Xue L., Constitutive modeling of void shearing effect in ductile fracture of porous materials, Engineering Fracture Mechanics, 2008, 75(11):3343-3366) to John Hutchinson's modification (Nahshon, K., Hutchinson, J.W., Modification of the Gurson model for shear failure. European Journal of Mechanics A/Solids, 2008, 27:1-17).
