R = 1000 // mm - radius of the cylinder
t = 10 //mm - thickness of the cylinder
p_in = 0.80 //Mpa- Internal pressure
E = 200 //Mpa- youngs modulus
v = 0.25 // Poisson ratio
//calculations
Stress_1 = p_in*R/t //MPa -Hoop stress //From derived expressions
Stress_2 = p_in*R/(2*t) //Mpa- Longitudinal stress
e = Stress_1*(10**-3)/E-v*Stress_2*(10**-3)/E
dia_change = e*R //mm- The change in daimeter of the cylinder
