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.

Postdoc Position in Chile

The Superior Councils for Science and Technological Development of Chile will call for the FONDECYT Postdoctoral Grants Competition.

The available grants are for 2 or 3 years. The applicants must have obtained their Doctorate degrees between July 2009 and June 2012 (the exact dates will appear in the page of the agency later on).

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

please,very urgent for master

research

i worked on punching shear of flat slab.

i used concrete smeared crack model all is ok, but i need two things just two

1)how can i show the crack(crack,conf)

2)how to get the ultimate load and draw with the central deflection

just that

thank you
