I did a quick check of your model and got similar results. I would take care with sharp edges, though, as that may skew your results in a FEA simulation.
Which equation are you using specifically for calculating bending stress? I have no idea what you mean by "ASME VIII 13".

Can you post a figure showing your mesh overlaid? You can do this by going into the stress results settings and selecting "mesh" from the dropdown menu within.

We typically have good results with Solidworks FEA, albeit it is annoying you can't specify the mesh type in the mesh control settings so that you can get away from tets. Personally, I would have simplified the model and done an analysis using Abaqus with a much higher degree of element control...
If you're looking for small volume and very high accuracy/precision, get an SLA printer as opposed to a typical FDM printer. We have both and use Flashforge Creator Pro's for our FDM and a professional grade system for our SLA.

I mean, sure. You can design any type of vessel you want. Whether or not your client will be able to maintain their insurance or whether or not the vessel is actually safe is another question entirely. I don't know what insurance/safety requirements exist in Asia so I'll avoid speculating on...
Vessel rerates can be performed via a Fitness for Service evaluation based off of inspection data if you want to avoid doing another hydrotest. See API-510 5.8.8

Googling that exact question led to 4-5 answers pretty easily. I'd suggest doing that or using the search function on here.
Also, the answer can change significantly based on the vessel you are building. Is there a reason you are using legs instead of a skirt?

You should post this in another forum, but the tool you're looking for is called Split.

When a line is coming down we often go ahead and replace the spring cans if they have been in service for a given amount of time, with that time depending on the service. The cost of the cans is nothing compared to shutting down the unit if one fails while in service. If there is a particular...
Sorry for the late replies!
"What did the manufacturer reccomend for routine inspection and maintenance? Was that recommendation followed before experiencing the failure?"
There is no routine inspection and maintenance on this component as it is located within the oil pan on the bottom of the...
It looks like the post in the General section of Mechanical Engineering was deleted.
Here is the link I had posted in that thread, for reference:

Having the ability to understand and perform hands-on work is something I think helps make engineers better at their job. I re-purposed the old driven gear from my outboard engine as a talking piece about this point and keep it on my desk to remind me that even small design decisions can lead to...
Our payment terms are structured by the size of the PO we receive. These don't always end up being the final terms, as we're willing to modify payment timelines for our larger clients simply because they provide a large percentage of our business.
Anything under $25,000 is NET30.
Anything...
To be honest, I have no idea as I've never had to contact them. Most of the questions I've ever had relating to the software had more to do with finding where a specific button was and generally a quick google search could alleviate that. I've never used PV Elite and DesignCalcs so I can't...
You could always design them by hand.
We use Compress to design new vessels in our office. I'm unaware of anything outside the ones you have listed.

Hey Startto,
I edited my post to reflect Watts as opposed to kW, guess I wasn't paying enough attention the first time around. Sorry about that.
Power is simply the work done per unit of time or P = W/dt.
A watt is 1 joule per second which is equivalent to 1 NM/S.
So to get power in Watts...
Hey M.hmk,
Can you clarify your question some? What are you trying to accomplish, specifically.
Are you trying to calculate stress/strain at a singularity for a specific purpose or are we theory-crafting?
If you're interested in this area, I would recommend checking out a book about fracture...
Spring variability is the difference in loading divided by the operating load (typically (HL-CL)/HL).
As your variability increases, your distance of travel increases, altering the load on the pipe as governed by Hooke's Law (F=-kx). If the component being supported was to be designed for...
I'm not familiar with pressure vessels for human occupancy as they are not covered by ASME B&PV codes but rather ASME PVHO-1. I'm also not familiar with the European codes either (PD5500).
You could try looking in ASME PVHO-1 for a possible solution to your issue or hopefully someone with...
