Talk:Sheet metal

From Wikipedia, the free encyclopedia

The way this is written, it implies sheet metal has only been around since 1500 AD... pretty sure that's not true... Yeah I'm pretty sure the Japanese had that covered since day one.

[edit] What about suits of armour?

They pre date 1500. If you consider things like breastplates and helmets it is more like thousands of years before 1500AD.

Sheet metal is a product of the industrial revolution. The article is not discussing forged products, or thin metal in general. Sheet metal is the specific product produced by rolling lines: long, thin, and coiled metal hundreds of meters long. - Toastydeath 01:27, 30 July 2007 (UTC)

[edit] embosses and beads on sheet metal

can any body tell that how on sheet metal , geometry and numbers of embossments and beads are determined59.160.18.209 (talk) 05:56, 2 June 2008 (UTC)

Please elaborate, because I don't even know what you are asking here. --Wizard191 (talk) 15:05, 3 June 2008 (UTC)

for example on the car platform ,how are no. and geometry of embossments are decided? —Preceding unsigned comment added by 59.160.18.209 (talk) 10:33, 4 June 2008 (UTC)

It's probably done based on geometrical constraints and FEA analysis. They used the FEA to figure out optimal depth to gain the most nominal stiffness. It's also dependent on manufacturability. --Wizard191 (talk) 15:50, 4 June 2008 (UTC)
