    Name The Process.

    I am having a steel sheet of 0.8 mm thickness. Now I want to punch it so as to produce a protruding surface. The depth of protruding surface is 5 mm. Should I call it embossing, stamping or what?

    We use a lot of this in manufacture. If it is a perforation with raised edges, it is done in two stages. First smaller size holes of the required shape are punched. In a second operation the holes are enlarged to the drawing size with raised edges by an extrusion tool.
    If there is no hole, then we use a single step embossing operation provided that the projection is not more than about 2 mm on a 0.6 or 0.8 mm sheet.
    Larger projections may need a forming or drawing operation.

    Is there anything to find the thickness of a perforated sheet which will be under flow pressure.???

    Not clear. Do you want a means to calculate thickness of a perforated pressure to with stand some maximum pressure or some way of measuring the thickness of a plate already in service and not accessible for physical measurement?

    The process is in strainers where the perforated sheet is designed to filter the debris. I want to calculate the thk of the perforated plate under pressure/stress.

    Then the equation in my post should help.

    In my reply to your question I had given a link, which I repeat:

    The equation in that site should solve your problem. You may have to approximate for the beta in the equation. What I suggest is that you can try with beta = 0. That will give you a slightly larger thickness. Otherwise find the total area of all the perforations, find the diameter of a circle with the same area and use that value for d in beta = d/D. You must get values for shear stress for the material of the disc that you want to use as also other values like diameter D of the disc.

    The correct term is Forming, however if you are using heat the term would be Forging.
    Stamping is if you were cutting out circular portions of the sheet. Embossing is used to create more intricate design on sheet metal where the sheet is fed through matching male and female die rollers.
