PhD positions in Computational Mechanics at the University of Salento in Lecce, Italy

Submitted by Laura De Lorenzis on Wed, 04/04/2012 - 06:46

3 PhD positions are now available at the Department of Innovation Engineering at the University of Salento in Lecce, Italy. Funding is provided by the European Research Council Starting Researcher Grant project "INTERFACES-Mechanical Modeling of Interfaces in Advanced Materials and Structures".

The successful applicant will work on topics related to computational methods for interface modeling, isogeometric analysis, and multiscale methods.

Applicants should possess the following qualifications/attributes:

Postdoc in MD Simulations and Theory of NanoFriction (Erio Tosatti's Group, SISSA, Trieste)

Submitted by vanossi on Tue, 04/03/2012 - 20:20

Dissipation Phenomena

Phase Transitions

Funded through SNF SINERGIA Project ‘Understanding nanofriction and dissipation across phase transitions’, we open in SISSA a postdoctoral position (‘assegno di ricerca’) in the area centered around nanoscale tribology (friction, dissipation, adhesion, wear) involving modeling, theory, and molecular dynamics computer simulations of nanofrictional and nonlinear dissipation phenomena, especially in presence of continuous phase transitions.

hi,

i am doing cutting simulation, but not able to produe the chips i known the johnson-cook damage parameters and all the required parameters, i am confused with weather .inp file to run in ABAQUS/Standerd or Explicit,

[ABAQUS] Through-wall crack in a pipe

Submitted by P. F. C. on Tue, 04/03/2012 - 11:25

Hi iMechanicians,

Currently modelling pipes, I am trying to calculate J-integral for through-wall crack. I do not use XFEM method since it does not work very well with elastic-plastic materials then I use the classic approach and I must sketch a precise mesh around the crack tip, which is perpendicular to the external (and internal too) surfaceof the pipe.

Ansys help - simple flow rule analysis

Submitted by koolraj09 on Mon, 04/02/2012 - 18:09

research

Hi all.

I want to analyse a plate with a hole using ansys. But it has a material non-linearity. The stress strain law I want to use is σ = K _εⁿ
I want to know how it can be done. I've seen and tried ansys but it has options like kinematic hardening etc... but how to incorporate this relation...please guys it's urgent!!

Thanks.

energy dissipated in a cantilever beam

Submitted by negarkz on Mon, 04/02/2012 - 10:42

Hi there ,

I am using modal analysis in abaqus to analize a cantilever beam that is subjected to an axial force. the material is elastic and Reighley damping is zero , but in order to define the parameters for analysis , there is a 5% damping for first mode. now , I want to obtain the dissipated energy of the beam through time. which energy output corresponds to the dissipated enrgy?

Is there a way to obtain the dissipated energy in elastic model with no damping at all?

Abaqus tire wear analysis

Submitted by Joe Elliott on Mon, 04/02/2012 - 09:33

ABAQUS/CAE

Hi all,

I am trying to complete the tire wear analysis example problem in the Abaqus user manual but I am having trouble with the input files. I have fetched them from the zip file using the fetch utility and I can import the first file (treadwear_axi.inp) in to Abaqus 6.9 but I am unsure how to continue as the other files do not appear to be complete.

Could someone please suggest to me the next steps to inport the remaining files and run the analysis.

Many Thanks

Joe Elliott

Dependence of R on C

Submitted by M. Jahanshahi on Mon, 04/02/2012 - 09:29

Hi All,

I think that the problem of R (Rotation Tensor) and C (Right Cauchy-Green Tensor) dependence is interesting enough to raise it once again. I have been reading the following paper

R.T.Shield The rotation associated with large strains. 1973
