Asked by qwerty
A cylindrical pressure vessel, with a diameter of 40cm and a wall thickness of 10mm is made of steel (isotropic, with Young’s modulus = 200GPa; Poisson’s ratio = 0.28) and is pressurized to 20MPa. The longitudinal and hoop stresses in the wall, σl and σh, respectively, are given by:
σl=pr2t
and σh=prt
What is the strain in the radial direction, through the thickness of the pressure vessel?
σl=pr2t
and σh=prt
What is the strain in the radial direction, through the thickness of the pressure vessel?

it's almost good
-8.4 *10^X*
*find correct X :)
epsilon_r=-ni*epsilon_h-ni*epsilon_l/E
epsilon_h=sigma_h/E
epsilon_l=sigma_l/E
-8.4 *10^X*
*find correct X :)
epsilon_r=-ni*epsilon_h-ni*epsilon_l/E
epsilon_h=sigma_h/E
epsilon_l=sigma_l/E

I can't understand the epsilon r, could you write it again? because it seems
- nu ?(epsilon h - Epsilon L/E) and this is not unitless
- nu ?(epsilon h - Epsilon L/E) and this is not unitless
