Hi, Quick question: What types of sand do usually go through a oil pipe? Thanks.

Hi, When I import an assembly into Ansys, it automatically creates connections. (I make sure that the setting under: Tools > Options > Connections > Auto Detect Contact on Attach is set to "Yes".) Next I change the names of the connections so that they are renamed based on definition. I now...

Hi, KD-621 in VIII Div.3 states that: - The average primary stress intensity based on the root diameter should not exceed: 1/1,8 * S_y. - The primary-plus-secondary membrane stress intensity: 0,75 * S_y - The primary-plus-secondary membrane plus bending stress intensity: S_y Say that I am...

Hi, Here's what I'm working with: http://i163.photobucket.com/albums/t282/Calc_photos/ExcelHelp01.jpg I have made a list of the different temperatures using Data>Validation. Using vlookup I've connected the temp with the yield stress values. I would like to hide the grayed out values. How can...

Hi, I've made a list using the Data>Validation tool. I was wondering if it was possible to make the drop-down icon (downward facing arrow) visible when the cell is not selected. Thanks.

Hi, I have made a small database of different material types in excel. First column contains the name of the material, and the other columns are material properties. I would like to make a drop-down list where I can choose a material and have excel automatically give the material properties in...

Hi, I have a bit of a dilemma. Say I have a section of thick-walled pipe with two blind flanges that is to be pressurized to 22,5k psi. I now want to penetrate the pipe wall so that I can add an instrument. The instrument consists of a flange that has a hole in the middle. I want to take a...

Hi, I was wondering if anyone has done a FEA and met the criteria given in KD-230 of the ASME VIII div3 2008a standard? I am puzzled by he total accumulated damage that needs to be defined. Any help on this subject would be greatly appreciated.

Hi, I have made an model symmetric around an axis from which I would like to extract a 2d surface. I've revolved several parts 90degrees and assembled them. I would not like to use the surface for FEM analysis. I know there is a way to do this in SolidEdge, I just can't remember how. Anyone...

Hi, I'm comparing the basic design requirements from 2004 with 2008 and have found some changes which I do not completely understand. KD-240 Elastic-Plastic Analysis from 2004: b) A design margin of a t least 1.732 shall be applied to the load that causes the strain to exceed 5% at any point...

Hi, I am getting some funny results when using thermal condition. I just put a uniform temperature on, not higher than 225degC (437degF) and run a Static Structural analysis to look at the von mises equvalent stresses. I have one fixed constraint, and no other forces/moments. The material is...

Hi, I am looking for any resources on Elasto-Plastic analysis using Ansys (both workbench and classic). I will mostly be using Bilinear Isotropic hardening to do elasto-plastic analysis of parts/assemblies made of different types of Stainless Steels. Any help is greatly appreciated, thanks.

Hi, I have an assembly model in Solid Edge which I want to export to a .step file. How can I export such to .step such that when someone opens it in Solid Edge they can only view the model as a whole, and not be able to select individual parts? Thanks

Hi, I'm looking at the possibility of connecting a cylinder made of Zirconia and a steel housing made of Inconel 625 by heating the steel housing. The steel housing is a simple pipe with a outer diameter of 50mm. The Zirconia cylindre has a diameter of 40mm and is 40mm long. The connection...

Hi, lets say I have a pipe section with a threaded bolt screwed into it. The bolt is now perpendicular to the length of pipe. I then pressurize the fluid/gas inside of the pipe. If the pressure inside is, lets say 10 000psi how much pretension is recommended? I have a copy of Machinery's...

Hi, I need to insert a ceramic (Alumina, Zirconia) inside of a steel housing. The piece is cylindrical. I have done some reading about brazing, and this is an option, but I am wondering if there are other ways of accomplishing this? Thank you.

Hi, I have a pipe section of peek with a bore trough the pipe wall. I'm going to put some kind of penetrator trough that bore. Let's say that the penetrator is made of titanium. A combination of high temperature and pressure will make the peek very unstable compared to titanium. I have tried...

Hi, Can salt be dissolved in oil? I just heard this, and don't know how this is possible.. Any papers, links etc are appreciated. Thanks

Hi, what are semi finished bolts? I've done a google search with no luck. Thank you

I work at a company with no metallurgists, so there is no one to bother with my questions. The customer often sends me info about Co2 (mol%) and H2S (mol%), along with temperature and pressure and asks what kind of material they should use The only thing I know how to do is calculate the...
