I'm trying to understand elastic deformation using the Lie derivative. I've read a good summary on Wiki but want other sources to review. Can anyone offer any sources &/or explanations. I need something fairly basic. Thanks, John.

 I hope that the mecanicians can help me to solve my problem.

 Is there any possibility to match the frequences of the physical model to the mesurement data?

Hi, I'm Pietro, a short term Italian incoming student at VT (virginia tech).

My advisor, in order to start my thesis there about skin friction coefficients in a scramjet combustion chamber, gave me a Modal analysis to do on a gage described as follow:

a cantilever beam  (1mm diameter and 3cm long cylindrical shape) with 1mm depth and 1cm diameter cylindrical flat "hat" attached upon.

Base constraints: zero displacements, zero rotation

Two positions are currently opened in Cardiff: http://www.cardiff.ac.uk/jobs/engin/lecturer-in-civil-engineering-2-pos…

 I strongly encourage imechanicians to apply.

 Best wishes,

Stephane

Abstract

Hello all,

I want to simulate Rolling Contact Fatigue in Ansys Multiphysics. I am
not sure whether we can perform this task in Ansys Multiphysics. Can
anybody help me regarding this? Is that possible to get S-N Curve as
result? Please help me..

Dear Colleagues,

a new 30 min IOSO video tutorial is available for you on-line: http://vimeo.com/13029874 Step by step Optimization task solution with the aides of DS SolidWorks (parametrizator), ANSYS Icem CFD (mesh processor), ANSYS CFX (CFD software) coupled with IOSO 

Dear members,

I am a newbie in FEAP and I would like to perform transient heat transfer analysis followed by a series of static analysis using FEAP.  Where does FEAP save the temperature history from the transient analysis and how to use this as input for the static analysis? I am using user constitutive model and most of the material parameters are temperature dependent. Which file do I need to include?

Best regads,

Vivian Tini
