Multiscale computation and modelling of granular materials

 

The energy/bio/nanomechanics group under the direction of Prof. Xi Chen at Columbia University is looking to recruit a highly motivated and independent postdoctoral researcher to study, based on computational nanomechanics and multiscale modeling, the mechanisms of energy absorption, conversion, harvesting, and storage using nanomaterials. The initial appointment is one year and the position can be renewed based on performance.

 

I would like to bring your attention to the Gordon Research Conference (GRC) on Adhesion Science, which will be held from July 24 – 29, 2011, at Bates College, Lewiston, Maine, U.S.A.  This conference is chaired by Chung-Yuen Hui at Cornell University and Kenneth Shull at Northwestern University.

My book on metamaterials, "An introduction to metamaterials and waves in composites" has been published on June 16, 2011 by CRC Press (Taylor and Francis).

The book is meant for students, researchers, engineers, and educators who want to get a basic grounding on the theory that is the basis of recent excitement about negative materials, cloaking, transformation optics/acoustics and other wave phenomena in composites.

The word "failure" can mean different things to different people.  Over the past couple of years, my interactions with various groups from industry has shown me that for some people failure means catastropic fracture/buckling while for others it can mean highly localized plastic yielding.  Even for relatively simple sandwich composite structures, there is no clearly agreed upon definition of the word.

Dear colleagues,

The deadline for the registration and submission of one page abstracts has been extended to the 21st February 2011.

XFEM 2011 is one of the successful series of

ECCOMAS thematic events.

XFEM 2011 is a medium-size conference

with a balanced participation covering both the theoretical aspects of the subject and engineering applications.

Objectives

Good morning,

I'm trying to simulate delamination with interface element, with a traction-jump law.

In order to see the Behaviour of the Interface element before the delamination occur, i introduce one interface element (8 nodes ) between two normal linear elastic solid element (quader with 8 nodes also).

I think the strain in the interface corresponds to the Jump

I have many difficulties:

Hi there ,

 I'm a researcher from UNSW sydney .

 I'm working on the elastic-plastic-creep based on the exhaution of energy density.

 I've came with a new idea for plastic collapse ,which is based on the exhausion of enrgy .

 The work is not yet publish , because I would like to ask your help here .

 Does anyone know or would like to help me to have an APDL file for plastic collapse analysis in ANSYS

Thanks for advance
