A thin walled spherical pressure vessel made of a linear elastic isotropic material has inner radius r and thickness t before pressurization. When subjected to internal pressure p , elements of the pressure vessel wall experience a state of stress described by a single point ( , ) ( /(2 ),0) pr t στ= in Mohr’s circle. The reduction of the wall thickness due to pressurization
- A. increases with t
- B. remains independent of t
- C. decreases with t
- D. depends on the elastic properties. Z Wall Aluminum cube Wall X Y 0.2 mm m C D B K M A 0.3 m 0.3 m 0.2 m
