aeroelastic of blade with abaqus

Submitted by attash3099 on

hello

i have a problem,i am trying it about one years

is:aeroelastic blade of helicopter with abaqus

i find some method for solution:

1.using abaqus for 2D ANALYSIS of cross section(meshed cross section) and then  1D  modal analysis modal,then using ZAERO for aerodynamic load,my problem in case is:linking abaqus and zaero.what is solutin method?

Material model 58 on LS Dyna

Submitted by konanur on

I am trying to use material model 58 of ls dyna to simulate a drop tower test on a carbon fibre epoxy composite. However i am getting poor simulation results with very high eroded internal energy values for composite.  My parameters are as follows

 

Hollow composite cylinder (with quad shell elements) of thickness 5mm with a mass of about 120g.

Impactor of weight 82 kg with impact vel of 6 m/s (direction along the longitudinal of composite cylinder)

material model in ls dyna : MAT 58

Extended finite element analysis tutorial in ABAQUS

Submitted by tvpc22 on

Hei,

 I am a new learner of XFEM. I want to start some exmaples in ABAQUS. The tutorial in ABAQUS is rather crude. If any body has experience, May I have small notes on how to solve problems with XFEM in ABAQUS?

Thank you for your help.

Multi time scale simulations for wear prediction in micro-gears

Submitted by vh on

Reliability of micro-gears is known to be adversely affected by wear. In this work we report a strategy to predict local wear with the aim of predicting their effective life span. For the prediction of local wear we start from the relevant model experiments, choice of a suitable wear model and identification of the wear coefficient from these experiments. This wear model is then implemented in an efficient finite element based scheme to predict local wear.

VAPOUR PRESSURE

Submitted by mahesh mane on

While thinking about the vapour pressure i can't get the relation between the vapour pressure of the water at 100 degree celcius (say water kept in container open to atmosphere)& the ambient pressure (i.e. 1 atm pressure)

           So please help me about it if posible... 

Expert programmer needed for atomistic project in Minnesota

Submitted by tadmor on

Expert programmer needed for an exciting project at the University of Minnesota involving the establishment of an online infrastructure for the evaluation of the transferability of interatomic potentials used in atomistic and multiscale simulations. The project called KIM -- the Knowledgebase of Interatomic Models -- is funded through the NSF's Cyber-Enabled Discovery and Innovation (CDI) program. For more information see the attached PDF file. The position is available immediately.

PhD thesis Evaluation

Submitted by kirthanlj on

Sir,

one of my students is working on PhD topic " Study of cold hole expansion and evaluation of fatigue properties on critical aerospace components". His work has to be reviewed by professor of non indian origin in foreign universities. I request you to kindly help this student. If you are interested, let me know, so that I will ask my university to contact you in this regard.

Thanks
