I need a formula for deriving the required material thickness for an acrylic panel. The project will involve an acrylic window for a large aquarium. I have included a dimensional rendering. The maximum design stress must be maintained at or below 800PSI. The maximum water pressure...

Possible design problem. Well this is the design that I came up with today. (picture 1) Here is the potential problem. The way these joints are made leaves a small lip on the outside edge that prevents them from recessing all the way into the holding jig. Thus they have to be positioned...

256bits, Thanks for your feedback. I also think that the set up in picture 4 is more promising. Thats what I was thinking. If the pressure gauge reads 1000 PSI the head of my piston is exerting 1719 LBS of force over a 2" DIA (3.14 sqin) which means that 547 PSI are exerted in that space...

Hello, I am using a hydraulic shop press, to test the strength of acrylic weld joints. Here are my questions. -I replaced the pressure gauge that was included with a very precise digital gauge. The hydraulic piston that presses down has a removable circular head 2” DIA. Its neck is 1.48”...
