Hi guys

I want to simulate a problem with abaqus,but during runing of my project,percent of process not increas for axample when i change mesh sizes to biger runing go up to 50 % and when i change mesh sizes to smaller than the previos size,it occure again but in 25%

is there any one that know about this problem,i'm trying to solve it for 2weeks but i cann't.

I'm waiting for your suggestions...

Application deadline: Sept. 24th 2010

Project Description:
Conventionally designed robots are made of metal parts, bearings, levers, gears or other components that are assembled with fasteners and screws, to obtain the desired functionality. An alternative approach is to derive this functionality directly from the properties of the materials and to embed components as, for example, with shape deposition manufacturing. CAD and FE simulations are essential tools to design and optimize the details of the robot's shape.

Hello all,

I need to mount an accelerometer in the test rig for dynamic measurement (machine condition monitoring). I am using MMF make KD41V accelerometer. The machine has limited space and I have to protect the accelerometer from splashing oil due to continuous lubrication. Due to space constraint, i have came up with a design in which a 25mm long, 25 mm diameter hylam material block is used in between machine face and accelerometer. Hylam material acts as insulator too. My question is, if i use such a long material in between accelerometer and machine face, will it affects the reading? Schematically this is shown in the following figure. Please guide me!

FATIGUE CRACK PROPAGATION-- ITS IMPORTANT

Hello,    

          Currently , I am working on the fatigue crack propagation in ANSYS 12.1. Can anybody help me regarding how to get the next cracktip position?
Currently, I am referring to the paper named, “Mixed mode fracture analysis of aluminium repaired panels using composite patches” , Authors : Hossein Hosseini-Toudeshky, Bijan Mohammadi, Hamid Reza Daghayani.

could somebody help me to get a paper,named 

I'm hoping that someone can share the physical significance (i.e. type of motion) resulting when the (spatial) velcity gradient L is constant. I'm not certain if L constant wrt to only position or also time. Gurtin (The Mechanics & Thermodynamics of Continua, pp. 107-08) uses this assumption to develop the motion equation given below.

I think (?!) that the resulting motion can include rigid body and uniform stretch but not sure. I'm also wondering if the exponential term, additive decomposition of L into spin & stretch rate, & multiplicative decomposition of F into F = RU = vR suggests a Lie group/algebra relationship for this motion. 

Thanks, 

John

Hello

I was analyzing pavement subjected to traffic wheel load. I was using the load as cyclic pressure. Suppose an amount of pressure with 200 different time frame. But I am not getting the right result as measured. So, would you please help on applying moving load? How can I assigned that load as moving load? where can I find the step load function? how can I determine the initial increment? is it more realistic to simulate the wheel load as dynamic? how can I do that?

Hi

 I am facing some problems with FRANC3D 3.2 as my getting different errors. Does anyone has the older version of FRANC3D i.e. version 2.6.

Furthermore all the manuals are for older version.

Kindly let me know if anyone has.

Thanks

hello all,

i modeled a cantilever column with eccentric loading to simulate half of ordinary column, i get a small displacement at cantilever tip (equals 1/3 of reality,) so i want ahelp a bout updating geometry during analysis in order to getting effect of second order/nonlinear effects due to eccentric load.my software is ANSYS

thanks for all,

for contacting or sending any information my e-mail address:hany_well70@hotmail.com

best wishes.

 Hai,

 i tried to apply hydrostatic pressureon a plate.But the input file showes,it is distributed load .how can i get correct figure i.e, uniformly varying load on the plate

Dear All

 I have a problem with some theories in plate analysis such as bending and buckling of plates.

 you know that in various theories of plates, equations have different order and different number of boundary condiotions must be apply. for example in classisal theory of plates we have 4 B.C.,  and in first order shear deformation theory the number of B.C. are 5.

I am confused, how should I recognize the number of required B.C. in each theory?

Hello,

      Im doing my M.Tech project on 'Analysis of grinding using nano cutting fluids with ANSYS" .  But ANSYS has to work at nano level.. So how to make programming to make ANSYS to use to solve nano level problems.

Hi,

I am modellling a beam with a  hole in ABAQUS and runs pretty well. Now I would like to model a small area of the beam.

For an example the rectangular area which has been shown in the attachment file. When I model it What should I put as a boundry

conditions ?. I know that you may say that reactions of the beam (namely, Moment, shear, axial force) but I would like to just

investigate this part under pure bending and shear. What should I do? 

A model without  support is unstable ????

It is a crazy idea but how could it be followed?

Thank you,

Parisa

Dear firends,
I run some abaqus input files and got my odb files(for example 100 odb files in a specific folder with the name of try). I want to extract LPF (load proportionality factor for whole model) using python script (In my analysis I used static riks). I used the following commands but when I run my script I get an error :
