Screen Strength
Screen Strength
(OP)
Dear All,
Here is the scenario:
There is an expanded metal screen (steel G550) with diamond shaped openings. An example is at http://www.dexmet.com/Expanded-Metals.html
I know the basic dimensions of such as screen LWD, SWD, SWO, LWO, thickness etc..
The question is if a given expanded screen can work for 1.2kN/sq.m pressure?
Effective span = 1.25 m, height is 1 m.
How to find this screen strength? Any formula, reference, calculator shall be very helpful.
Thanks,
-DKG

RE: Screen Strength
Why not contact the manufacturer?
RE: Screen Strength
Desertfox has given you good advice; Contact the manufacturer, or at a minimum find a matching product in a catalogue and use 70% of that value as a check.

In this case i want to manufacture this. Existing manufacturer are not providing this info as such. Moreover, i would like to learn the physics/mechanics behind the calculations.
RE: Screen Strength
If you want to make things more complicated you can include factors like stress concentrations at the sharp internal corners of the diamond mesh openings. Or you can consider the effects of structural stiffness and deflections on the stress levels produced at the fixed perimeter of the screen.

What is the opinion of expert on this...how can i further improve it make them more credible and robust....
Appreciate your insights...
