I've been doing some research on stainless gauges (archaic) recently to try to find what the actual standard nominal thickness is for each one, and which ones are commonly available from suppliers. It has been quite frustrating and a little surprising/enlightening. Below is what I've found -...
We don't call-out rivet lengths on drawings. We specify the rivet type as far as possible and then put XX for the length e.g. MS20615-4MXX. The quantity in the BOM is "as required", and we stock a selection of lengths that are reordered at a minimum quantity reorder point. Rivet lay-out is...
Me again. Take take take.
I need the temperature dependent values for Sm (now Sps I believe) from the ASME BPVC for Inconel 625 annealed sheet.
It's not in the 1986 edition. I've been told that it does exist in the later versions, which I don't have.
Typically, I believe temp dependent Sm...
Hello all,
This question could sit in many a forum, so I'll put it here and see what happens.
In the austenitic stainless steels section of MIL-HDBK-5, Table 2.7.1.0(b), reference to CRES 321 has been omitted in rev J (i.e. AR-MMPDS-01). It was originally included in H. There is no rev I.
I...
Hi,
Please can anyone give me the 3Sm (now Sps I believe) allowable from the ASME BPVC for Inconel 625 annealed sheet? It's not in the 1986 edition. Is it even in the later editions?
Thanks,
JE.
Hi,
I'm currently using Ansys and attempting to predict the fatigue life of a sheet metal structure containing many rivets subjected to a random vibration spectrum. I am using 4 noded 3D elastic shell elements for the sheeting.
My first issue is how to model the rivets? I have used coupled...
A conservative method of predicting the fatigue life of a riveted joint is to extract nodal forces from an elastic finite element model with the rivets represented as beams, calculate the maximum sheet bearing stress using the quotient of highest load and rivet bearing area on the thinnest...
