Learn about how Simpleware software was used to aid in the creation of models for analysing the risk of cerebral aneurysm rupture in ANSYS. The results have been used to develop a clearer sense of how image-based modelling can help to better diagnose aneurysm risks based on the mechanical properties of tissue.

In recent times, mechanical metamaterials and a phononic crystals have attracted the attention of some groups, as they allow to exploit on a larger scale phenomena known from solid state physics, such as the creation of band gaps at certain frequencies. The peculiarity of metamaterials is that their effective properties emerge from the periodic geometric organization of their unit cells rather than from the constituting bulk materials. Furthermore, metamaterials can be built in any size, ranging from the nanometer to the meter scale, and out of any material to suit different needs.
With the hope that this write-up will be useful to researchers, students, and industrialists interested in working with IGA. The 3D code including enrichment for fracture mechanics can be downloaded on SourceForge

Cardiff University's endowment funds have accumulated sufficiently to offer three PhD studentships to full time students.
Funding is available on the following basis:
Full-time awards
1. Two x 3-year full-time PhD studentships where 50% of the costs (fees, standard stipend and project support) are met through the endowment fund and the remaining 50% will be match funded by the School.
In the laminar mode interactions
among molecules generate friction between layers of water that slide with
respect to each other. This friction triggers the shear stress, which is
traditionally presumed to be linearly proportional to the velocity gradient.
The proportionality coefficient characterizes the viscosity of water. Remarkably,
the standard Navier-Stokes model surmises that materials never fail – the transition
to turbulence can only be triggered by some kinematic instability of the flow. This
premise is probably the reason why the Navier-Stokes theory fails to explain

hi every one
I want to find stress intensity factor in crack by j-integral in abacus?
how can I do this?
thanks
Applications are invited for few open positions in the area of
multiscale simulation of fatigue and fracture of advanced alloys and
nano-material based composites. Primary focus of this research is investigation
of fatigue and fracture behavior of nanomaterials and to develope various
constitutive models for continuum, based on large scale atomistic simulations.
Research effort will include development of analysis and design methods toward
improving material/structural behaviour using computer simulation. Interested
candidates should have preferably MTech/ME degree in
mechanical/civil/aerospace/material engineering discipline with good knowledge
