Tom, I suggest you open a Support Request on Smart Support to receive specific support on this issue. Please include the exact version/build of c2 you're using in the request.

not to extract but it is possible to find out how many "nodes" have support on it. Go to stress isometrics, choose Edit Stress Annotations, then Restraint/hanger types. It will show you at the left the index, counting exactly how many "nodes" have su

is there a way to extract the number of nodes having support in a caesar model? example: node 10: +Z node 20: +Z, guide node 30: +Z, -X, +X in this example i need to know there are 3 nodes having supports. the caesar report extract 1 support for n

Hi Michael, you have made your point there regarding the heat loss. At the moment I can only assume a number. The max design of 110 deg C is mainly causing this. Would it be acceptable to assume the max temp for buried piping is the operating temper

Correct, CADWorx Plant component data can be found in the Xdata on the object and in dictionaries on the object. Then numerous dictionaries in the dwg file itself for program settings.

I know that CADWorx can connect with an external database through Live Database. But as far as I know, CADWorx does not have an internal database as such and relies on the existing, internal data storage afforded to it via the format of the .dwg fil

You could also put the elbows in an insulation box to allow them to move and install flexible / crushable insulation along a portion of the connecting pipe to allow the pipe to move.

I am trying to run the WRC 297 analysis and the analysis section is blank. Does anyone have the fix for this? It was working until I deleted the WRC107 item at the top of the component list and then it stopped working. Now it won't work at all. T

It is not very clear if you have in the SOW also the burried line. If you do not, you can specify that is included only for boundary condition and to delete the allowable. Other thing: do you have an anchor block underground? you can stop there. Man

If you have FEA Tools you can try to use it. Although it's not always a guarantee that it will reduce stress. If still overstressed, try increasing section modulus by increasing bend thickness, but noting the welding requirements for dissimilar thi

In an ideal world, you would forgo analysis in CAESAR, not because CAESAR doesn't give you the answer you need, but because you know CAESAR will predict what you already know. I would expect that the line temperature remaining hot could be a point y

I'll try to clarify a bit what this is about. I'm interested in carbon steel (EN 10220) and stainless steel (ISO 1127) pipes and welded fittings (EN 10253-2 and 10253-4) and flanges by EN 1092-1

To take the response a bit further, CAESAR will automatically calculate SIFs and flexibility according to the code. If you believe the SIFs and flexibility factors from the code to be inaccurate, then you'll need to calculate those externally and in

It's ok now Dorin. As I understand loading ratio is also related to mean stress. And since the fatigue curve itself have considered the effect of mean stress different loading ratio can be catered but with consideration to the cumulative usage for ea

Jump to new posts Ratcheting and Low Cycle Fatigue by Borzki @ 11/26/21 11:41 PM

Ratcheting is an incremental plastic collapse. When we satisfy the low cycle fatigue from ASME Fatigue Curves, is it necessary to check ratcheting? What is the main difference between the two? Your expert advise is highly appreciated. Warm Regards

Thanks Dorin for that precise information regarding mean stress. It clears my mind now. How about loading ratio? Warm Regards,

Hi Borzki, Quote from ASME BPVC VIII-2 Sect. 5.5.1.4: >. So, the common employment of smooth bar fatigue curves given by ASME VIII-2 part 5 do not require mean stress on cycle consideration. Best regards,

Take the nominal OD, multiply by 8, and enter that value in the "bend radius" field.
