Question

The ends of a thin cylindrical shell are closed by flat plates. It is subjected to an internal fluid pressure, but the ends of the cylinder are rigidly stayed and no axial movement is permitted. Determine the increase in the volume of the shell. Take Poisson’* ratio as 0.30.

Answer 1

Due to internal pressure, the cylinder tries to expand longitudinally. However, in this case, the ends are rigidly stayed, which means that the ends exert axial compressive force on cylinder, so that the axial strain in cylinder becomes zero. Due to internal pressure
