Hello, I am trying to model hoop stress of a cylindrical pressure vessel but my simulation values do not match theoretical values.
Hoop stress in a cylindrical pressure vessel is defined as (P*D)/(2*t) where P is the pressure, D is the diameter, and t is the thickness.
When I use this formula I am receiving a theoretical hoop stress of 13.25 MPa while simulation is giving me 2.8 MPa.
My parameters are P = 1 MPa, D = 53mm , t = 2mm
I am currently defining the stress plot to show normal stress in y direction.
Thank you in advance.
