Interface elements versus continuum elements
Hi,
I am modeling interface, its thickness is around 100 micron, I am modeling this problem in ABAQUS, my doubt is, can I use continuum elements like plane stress or plane strain to model this interface with conventional materail models available in ABAQUS or do I have to use interface elements with cohesive zone models. My main doubt is why should I use interface elements, whether plane or solid elements cannot handle interface, please can any body educate on this topic.
THank you

Fracture Mechanics
Hello...
Can any one help me in how to solve J INTEGRAL for simple 2D geometries.Atleast can anyone help me where can i get PDF files on J integral... Plz its urgent its a part of Thesis... Plz post your conmments at ravikumar_04333 [at] yahoo.com (ravikumar_04333[at]yahoo[dot]com)
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

low velocity impact on composite plate
HI,
I m working on low velocity impact on composite plate. Can anybody tell me after modeling plate in matlab how can i analysis it in Ansys software?
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.
