marc material on 2d orthogonal cutting

hai

i am a student who is working on marc in order to simulate the cutting forces (orthogonal),

so ppl plz do pass any material if u have any regarding this subject

my e mail id is p.pradeep@live.com

thanking you

Interlaminar Stresses

Dear Sir/Madam,

Interlaminar stresses in Composites

I have modelled Plain Stress problem in hypermesh(Input deck is created in Hypermesh to solve in Abaqus).Layup sequence is [0/90/90/0], am getting the Stresses( σ11, σ22, σ12) in top and bottom layers only, but unable to get the stresses at each Interface, If any one knows how to write the code, please reply back.

PhD/PostDoc position at University of Twente (NL): Hierarchical multi-scale modeling

The scientific goal of the project is to develop a multi-scale computational method that uses a single hierarchical data-structure as basis – involving also multiple fields. Starting from mesoscopic structures (particles or domains) a grid is constructed on a hierarchical, tree-based data structure. The hierarchical approach allows for micro-macro transition, coupling of different fields, and coarsening or refinement – where possible or needed, respectively.

I have a problem on shear failure for the material Ti-6Al-4v with ABAQUS

hello, every one

recently,I need to develop model on the material of Ti-6Al-4v with Abaqus, I will use both Johnson-cook damage and shear damage for damage evolution,however, i am confused on the parameters for shear failure:
1)the parameter "ks", i can't find this value on internet;
2)the fracture energy for damage evolution in shear failure, the value should be the same with Johnson-cook,help example gives the same value, but i think it should be KII value for shear fracture,not KI.

  I don't know if I have expressed clearly,  could you help me ?

Post Doctoral Position at Indiana University-Purdue University Indianapolis: Micromechanics and Multiscale Simulation of Vessels

Dr. Kassab’s Cardiovascular Biomechanics Lab (Indiana University-Purdue University Indianapolis, IUPUI) is seeking a post doctoral fellow in micromechanics and multiscale modeling/simulation of the mechanical behaviors of coronary arteries. The project is well funded by NIH. Please see attachments for description of the position  and abstract of the research plan.

Mellichamp Chair in Systems Biology, UC Santa Barbara, College of Engineering

Mellichamp Chair in Systems Biology. The University of California Santa Barbara seeks to hire a highly creative and productive individual to fill a Mellichamp Chair in Systems Biology. The opening has resulted from a philanthropic gift that has been generously donated by Duncan and Suzanne Mellichamp.

Candidates at all levels will be considered. The primary academic appointment will be in either Mechanical Engineering or Electrical Engineering, with a possible joint appointment in a related science department.

Strain Induced Growth Instability and Island Nucleation on Patterned Substrate

Strain induced self-assembly provides an attractive route to nanofabrication of semiconductor quantum dots on surfaces. Recent experiments have demonstrated that combining the strain induced self-assembly with surface patterning provides an effective method to further improve the size uniformity and spatial ordering of quantum dots. However, the underlying mechanisms responsible for such improvement remain poorly understood. Recently, we have developped theoretical models to elucidate the strain induced growth instability and island nucleation on patterned substrates.

Career opportunities for Computational Mechanics in Industries

Hello Everybody

I am S Phaneendra, a Computational Mechanics Masters Student at UPC, Barcelona. I will be completing my masters degree by June 2009. I am working masters thesis, developing a material model for composites. Can anyone pls do me a favour by listing a few industries which can provide career opportunities for me in the related field.

Thank You

 

Post Doctoral position at French research centre LMPM-ENSMA : numerical developement applied to multiphysic coupling

 

The LMPM (http://www.lmpm.ensma.fr) seeks candidates for a post-doctoral position in the domain of numerical development applied to the modelling of coupled phenomena. It consists in understanding, modelling and simulating the different couplings (like mechanical, thermal, chemical and diffusion problems) on industrial cases.

The LMPM is a research centre in France which focuses on  durability of material under severe environment (multiphysic coupling).

About osmotic pressure

Recently, I studied  Prof.Suo's lecture "Advanced Elasticity", node/725.

The following is explaination about osmosis pressure in the lecture.

ABOUT Work done by a pressure applied to a system

I have one question  about work done by a pressure applied to a system.  The book of Thermodynamics often always present pdV (where dV is the change in the volume of the system. )but never Vdp, Why is that? Is it because we don't treat p as a variable? In a grand canonical ensemble is pressure constant for any system?

Acording to Thermodynamics first law,  du=dq-dw , where dw denotes work done by pressure and external force.  dw=pdv+dw' .   dq=Tds (Thermodynamics second law)

so, dU=TdS-Pdv-dw' 

finally, dG=vdp-sdT-dw'

Is imechanica evolving into mechanics.craigslits?

Lately I am feeling like imechanica is becoming a craigslist for mechanics than a forum. Most recent blogs are simply ads that do not generate any discussion. Neither do questions from people get any reply, not any where near to what it used to be.

The last journal club had about five or so replies and the current one has no comment with two days to end.

Is it just me or does any body else feel the same too? I feel we have to think about how we can have a community here than just a repository of mechanics related stuff.
