Strength of Materials

SALIENT POINTS

• Fluid, gases or dry materials with or without pressure are stored in specially made vessels with small thickness but adequate enough to sustain the load and pressure.
• If the ratio of the thickness of the wall of the shell to internal diameter is less than it is known as a thin shell.
• In thin walled shells the pressure is uniformly distributed through the thickness of wall and the stress is computed easily.
• If the walls of the shell are thick, the pressures are no longer uniformly distributed and the problem becomes complex.
• Stress acting along the circumference of a cylinder is called the circumferential or hoop stress.
