The fillet weld strength limit state according to AS 4100 is determined by an equation where the tensile strength is used along side an inbuilt 0.6 factor in the equation and a 0.8 capacity factor for the fillet weld. Even though the equation is considering tensile strength, it is factored to a...
When working on a simple beam model the forces extracted from joints in that model show forces correlating to an acceptable weld capacity.
When the same structure is modelled with finite elements (plate/shell elemets), sometimes you might see that for this same joint a significant portion of...
Dear Experts,
We have developed a new welding procedure for our client however, they are not happy with the impact test temperature.
The minimum design requirement for the vessel is -29 degrees C therefore we impact tested the test pieces at -30 degrees C.
The client is saying that the...
Hi,
I'm having some confusion regarding the limitations of multiple openings according to AS1210. There are 3 clauses that talk about the distance between each opening and I believe each one can give a different answer. Can someone please provide some insight on the interpretation of each of...
Hi BJI,
Thank you for the response.
Yes, Aa is recalculated for every t and ID is considered to be the corroded ID.
You are right! I just have to compare that calculated value to the selected corroded thickness less mill under tolerance.
I have read AS1210 3.4.2 many times and I find it hard...
Hi Everyone,
I'm a recent graduate currently learning pressure vessel design. Im building a spreadsheet which determines the minimum thickness for a pressure vessel under external pressure. I hope someone is able to give me some feedback on what I have done until now. In this thread I'm...
