Prestigious 5 year Fellowship -- RAEng/EPSRC Research Fellowships
To all outstanding researchers with less than 3 years of post-doctoral experience, this is a unique opportunity to secure a 5 year post-doc.
This will be highly competitive, and applicants must be of world-class quality.
Topics available in our group:
- multiscale (fracture) mechanics
- microstructurally-faithful modelling
- surgical simulation
- coupled moving boundary problems
- meshfree methods
- quantum simulations
For more details, please see below, and contact me at
Postdoctoral Associate position available at MIT
A postdoctoral associate position at MIT is available immediately, in the broad area of atomistic, molecular and multi-scale modeling of hierarchical biological, bioinspired and nanostructured materials. Material properties of specific interest include mechanical properties, in particular deformation and failure mechanisms. The work will emphasize on mutable properties (mechanomutability, thermomutability) and the analysis and design of adaptive, responsive, and robust materials through the integration of scales, from nano to macro.
Stress invariants
This is a very fundmantal question.
What is the physical significance of stress invariants?
I understand that the stress invariant J2 of the deviatoric stress tensor is used to ecpress the yield criteria-but this is same as Von Mises yield criteria-I want to know what is so special about-stess invariants?
I understand that these invariants remain unaltered by rotation/transformation of the axis-is this the only reason for being so special or there i any other reason as well?
Anybody knows a molecular dynamics software for Windows operative systems?
Dear All,
I am looking for a freeware molecular dynamics software working for Windows operative systems.
I have tried LAMMPS, but it seems to me that it works only under UNIX.
Thank you very much in advance for any information.
Best wishes, Marco Paggi

Postdoc position at HKUST on computational mechanics/geomechanics
A post-doc position is available now for one who has recently obtained (or about to get) his/her PhD on computational
geomechanics or computational mechanics. The successful candidate is expected to have strong background of mechanics
and extensive experience on computer programming (e.g., coding in FEM and/or DEM), and is able to work independently.
He/she who has previously worked on multi-scale modeling of material behavior will be particularly welcome to apply. The
initial contract is one year and is extendable to multiple years subject to his/her performance and availability of funding.
Geometric factor for mode II stress intensity factor for a finite strip under under pure shear loading
The geometric factor for mode I stress intensity factor for a finite strip under pure tensile loading is reported in Tada handbook as F(a/h) = 1.122 - 0.231(a/h) + 10.55*(a/h)^2 - 21.71*(a/h)^3 + 30.382*(a/h)^4 , but in the existing literature, I could not find such geometric factor for mode II stress intensity factor for a finite strip under under pure shear loading. Does anyone know such geometric factor for mode II stress intensity factor for a finite strip under under pure shear loading, if it is reported in the existing literature? or, if it is available in any unpublished sources?
FEA Improves Reliability of Flip-Chip Packaging
On Aug 10, 2009, Semiconductor International (SI) Newsbreak published a report on my work in AMD about 3D fracture study of underfill delamination as the top story in that issue. I have never imagined that. Except the pleasure I received from this good news, I wonder if this work is also interesting to iMechanica community. For that reason, I attach here the SI news report and the original paper published on ITherm2008 Proceedings. Welcome any comments and thoughts.
