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