Hi there,
I am the administrator for an airsoft group based out of the Chicagoland area. Many of our members currently use mesh safety goggles of the sort used in arboriculture, wood chipping, and concrete cutting. These goggles do not have a specific impact rating (though the manufacturer does claim they are resistant to high velocity impacts), but the tensile strength of the stainless steel wire they are made from is rated at 65,000 pounds per square inch (as per the manufacturer). The projectiles our airsoft replicas fire never exceed 1.49 joules of energy (.20 gram projectile @ 400fps).
Is there anyone here who could tell me if there is a way to calculate how many pounds per square inch 1.49 joules will exert? I'm trying to calculate the relative impacts these goggles can take.
Thanks,
TF
