I was wondering if anyone could explain this behavior to me. The setup was I had a custom made fixture which was more or less a 3.75" high by 3" dia 6061 aluminum block put onto our compression testing machine here at work. I loaded it up to 14000lbs, and then unloaded it. Initially the ramp...
I posted this one over in the measurement forum, but have since determined that most likely the challenge I am dealing with though not specifically a composite operation is something that has been developed for the composite world.
Currently I have a process where I have a heated press that is...
I have a press that squeezes a material between 2 heated platens, in an ideal world I would love to see a thermal image of what is taking place between the press platens. In reality I could likely settle for thermocouples one/inch or so, but that would be a lot of inches at 36x36". Does anyone...
Looking through the ISO 4126-7:2013 I am 99% sure I have found an error on the attached graph. See my little markup you can see the error when it comes to their own example problem. Simply put I believe that they have the wrong label on the wrong axis. Several other sources out there appear to...
We are currently designing a system that is a little bigger than what we have done before and now are into a whole new class of valves. The system needs to be pneumatically controlled for explosion proofing requirements. The medium is ultra pure DI water with dissolved gas in it and rather...
I asked the question in another posting but really this is a second discussion so I think it deserves a separate thread. I am currently working on a project being developed for use in Germany and we need to size out the relief valves. LESER's (Germany's leading relief valve manufacturer)...
I have spent some time reading through Leser's manual primarily the Chapter 7 on sizing of relief valves. Between this and other discussions on this website it would appear to be clear that the mfg needs to give me the Coefficient of Discharge or Kdr (Certified Derated Coefficient of Discharge)...
