Hello all,
I have some doubts when I try to define my welding connection in Catia V5. Always you create a welding element between two elements, you've the possibility to select the type of the welding seam, this means:
- Rigid
- Contact
- Hexaedron
- Beam
- Rigid-spring-Rigid
-...
Hello all,
I am doing the calculation of a cooling system for a cryogenic magnet.
I would like to ask where can I find different values for the minor losses. I have already found some values for standard angles as 45deg or 90deg as well as for normal tees and wyes (45deg). Is it possible to...
Hello all,
I want to monitored (mass flow and pressure) a pipeline of 6mm inner diameter and 8 mm outer diameter. does anyone know a company which sells components for these sizes of pipes?
Thank you very much
Hello all,
I have made a FEM analysis in Ansys a Catia V5. I have different results and I can't explain why, I attach a picture first of one error in Catia that I don't understand so well.
The force applied had been 1000N.
I attach also a picture in Catia with the system analyzed where it's...
Hello all,
I have a questions, can be possible a heat transfer coefficient of 6 (W/m^2/K) between the air inside an office an a pipe of Polyurethane? I assumed natural flow convection. I have calculated the heat flow in a radial direction (everything is known: temperatures, thermal...
Hello all,
I want to use aluminium pipes in a cooling system in which it will reach -25ºC (243K) with water-methanol as coolant, can be this a problem because of the corrosions of the aluminium?. Also I would like to know if aluminium can be activaed by radiation, because this fact can be a...
Hello,
I have a doubt when I am calculating the maximum strain in a shaft. I have calculated all the diagrams (Bending momentum, Shear and Torsion momentum), Once I have it to calculate the maximun strain I am using the Mohr Circles. I attach a pdf file with an brief explanation of what I am...
Hello all,
I have a question about hiperstatic structures, someone knows how to calculate a hiperstatic structure like in the attached picture? All the examples I have are in a continuous beam.
Thank you in advanced.

Hello everybody,
I am looking for a carbon fiber with some specific features due to my project requirements.
I am considering to create by myself the carbon fiber so now I am focus on Prepeg. My requirements are:
Low thickness (0.2 mm)
Multidirectional fibers (90 degrees)
High thermal...
Hello everybody,
I need to know how can I calculate the minimun bending radius in a aluminum sheet? The sheet has a thickness of 2mm and the radius I want to bend is 90 degrees. Can someone help me?
Thank you
