Acrylic disk under pressure

Post by Jaman42 »

Link to calculator: http://instacalc.com/9335

Formula:

Code: Select all

σ =	3(3 + ν)pr²
——————
8t²

Where
σ	  is the maximum stress in Pa
ν	  is Poisson's ratio for the material (0.37 for acrylic from here)
p	  is the pressure the disk is subjected to in Pa
r	  is the disk's radius in meters
t	  is the thickness in meters
Found it on this site: http://jenswilly.dk/2013/02/calculating ... -at-depth/

*Edit: Also found this in the forums, thought I just add it here as well
