Hi everyone, I am doing a transient temperature & pressure load application in a pressure vessel. I have lot many data that I apply through table (Excel file). I am applying pressure on lines (the pressure of jth node is different from ith node). How to check whether the pressure load is...

Hi gentlemen, I am condidering 3 load steps in my problem in each forces are acting in x,y & z axes respectively. I could see at the end the summed up result. But if I am deleting the Y force after solving the 2nd step & applying Z force in 3rd step, I could not see the effect of Y...

Hi, Thanks for the replies & drej, the angular velocity command looks appropriate if we are considering single structure (i.e. Single roller). If it is needed for 2 rollers rotating with contact between them, what has to be done? Is there any options for giving 2 velocities for different...

Hi all, The DOF ROT in shell elements makes the node to rotate but i do not get the unit of that. If I have to rotate a disc at 5000rpm then what i have to do??? Any helps please... Thanks, Thiru.

Hi, I am doing rolling contact fatigue of two rollers. The rollers are running & one of the rollers is moved axially towards the other at high rpm. First I tried with shell63 only but could not find appropriate contact element between the rotating rollers(Node to node). Since Solid elements...

Can any one pls tell me how angular velocity is being taken in ANSYS. The option asks for velocity w.r.t global cartesian only. But I need to model 2 rollers rotating at different speeds(Contact analysis when subjected to axial thrust). How to go about...

Hi, This is the fact every contact problem faces. Theoretically your surface should not penetrate but most of the time you can see penetration. As told above increase the stiffness till unconvergence, then note down the penetration from the output window (you can see the tolerance and...

Thats not a 1D element. I hav used Beam4. That is a 3D line element. It has 6 DOF & MX can be applied. My question was to plot the shear/twisting stress in that elemnt. Anyone know please.... Thanks, Thirumalai.

Hi, I have done a contact analysis using conta174 & targe170(using contact wizard in ansys6.1). I have given contact stiffness factor as 0.5 & penetration tol as 0.1. While running, the output window shows contact stiffness=4382 & tol=0.387. What is the formula or equn inside the software and...

Thanks strendrive. Thats the way to do in 3D. I need to plot shear stress in a 1D line element Beam4. Is there command to plot that? Thirumalai.

Hi all, I am doing gear test rig design. My problem is to find the shear stress in a stepped shaft. I have modelled with beam4 (line element). I have searched in Element table for plotting the shear stress. But couldn't get. Is there other ways to see the shear pattern in a shaft? Thanks...

hi toohtaah, One more point i want to add. The values yield & ultimate you are giving are used simply to find the slope of the curve after yield. If that curve is plotted the program gets the stress value from the obtained strain. So the stress will be taken depending on strain...

I am applying a torue at the end of a shaft. I am using beam4 element in ANSYS. I have tried for plotting shear stress in "element table" option but i couldnt get that. Is there any way to plot the twisting shear stress in a line beam4 element? thanks.

hi tooh taah, You cannot tell the system to stop at ultimate since itz doing simply number crunching. so if the value found to be high then your model is failing subjected to your loads & BC.

I want to know the (formula) torque transmitting capacity of a universal joint. If possible th steps involved also. Thank you in advance.
