Pressure vessel from brittle materials
Pressure vessel from brittle materials
(OP)
I am looking for some guidance on designing pressure vessels with brittle materials.
Ideally, I would prefer to get info on ceramics. I do realize, however, that is probably not going to be very straight forward. Alternatively, I can possibly use principles involved in pressure vessel design with concrete.
I am looking for the appropriate theories of failure to be used, dealing with fatigue associated with pressure cycles, best practises with FEA modeling of such materials and so on.
Maybe someone in nuclear/civil engineering fields help me out.

Before venturing out on this type of journey, what are the design pressure and vessel contents?
RE: Pressure vessel from brittle materials
Good questions both.
Unfortunately, I do not have a big enough paycheck to be privy to this information. I am simply an errand boy for my boss on this. You will probably excuse me for the omission of this critical information.
We only have mechanical engineers here who have spent most of their careers in with designing metal parts or more specifically steel parts. So, this is particular task is a strange animal to everyone here.

Any kind of "Brittle material design" involves very large safety factors and hence a large cost of materials.
Being an "errand boy" responsible for FEA analysis of what may be a dangerous or hazardous vessel and being purposefully kept in the dark tells me there there are MBAs that lurk about in your organization

Your post did not help at all.
It is my understanding that the application requires nonmetallic materials. I am aware of the limitations of concrete, ceramics etc. Hence, my query specifically requests for guidance or references on designing with *brittle materials*. It is right there in the subject.
I need to know which industry codes, guidelines or books I can use as an aid to design.

As MJCronin indicated, the Design Margins for Cast Iron approach 10, vs. 3.5 for ductile materials.

a vessel made of glass is an accident waiting to happen
RE: Pressure vessel from brittle materials
I suggest that you might look into some heat exchangers which have phenolic-impregnated graphite components. The closest thing to ceramic components that I am aware of is silicon carbide tubing used in heat exchangers with extremely corrosive fluids. The only glass vessels I am familiar with are actually steel with glass linings.
I believe that most of these have something in common. The graphite exchangers use an extremely low allowable stress value, since the materials have very poor tensile strength properties, but are better under compression. They usually rely on more traditional materials for the shells. The ASME Code may have some guidelines available for these materials.

RE: Pressure vessel from brittle materials
Are you really wanting a pressure vessel made from brittle materials or are you wanting one made of non-metallics? There is a bit of a difference.

Either way, I am dealing with brittle, nonmetallic materials.
RE: Pressure vessel from brittle materials
as far as i know, everything is experimental prototypes for now and no one is building them commercially
I don't know if these research types will be willing to share their studies with anyone as i am sure they will be looking for patents to help pay for their research.
RE: Pressure vessel from brittle materials
This is one of many sites that have information on such vessels.

If you need ceramic, or such brittle material, for a vessel it must be because of the process. So, design a steel vessel and lined it with the ceramic or glass or whatever. This is how glass lined vessels are built.

Serious temperature limits because of the epoxy, as I recall about 350F.
These replaced ones made of Pt.

You might search under nuclear construction as there has been considerable work on prestressed concrete pressure vessels in that field.

We are considering sizes from 10" to 22" (ID). Can you elaborate about the ceramic vessels you mentioned?

I don't know about the newer types, both types prestressed and non-prestressed cement pipe.

There Nereus is unique in that it doesn't have a tether and is controlled from the surface by a torpedo wire.

To give you an idea what danger it represents using glass a pressure vessel let's see the following example:
Have you ever drop glass bottle, cup, or any other container? Now imagine what would happend if all this would be under 500 psi pressure?
RE: Pressure vessel from brittle materials
The advantage of using clad steels in pressure vessels is in the price reduction of the material used and in the Inspection & Maintenace Requirements and costs of normal steel vessels or full alloy vessels. But, this is all academic, so to speak, check in with the Alloy/Ceramic/Polymers Engineering Sections at Ohio State.
