A thin cylindrical steel shell of a diameter of 150 mm and a wall thickness of 5 mm has hemispherical ends. Determine the thickness of hemispherical ends, if there is no distortion of the junction under pressure. E = - 208GPa, v = 0.3
Thickness of the cylindrical portion, t1 = 5 mm
Poisson’* ratio, n = 0.3
For no distortion of junction under pressure,
