Thin-Walled Pressure Vessels Flashcards
1
Q
A tank or pipe carrying a fluid or gas
under a pressure is subjected to tensile
forces, which resist bursting, developed
across longitudinal and transverse sections.

2
Q
Formula of Tangential Stress
A
𝝈𝒕 = 𝒑𝑫 / 2t
3
Q
Tangential Stress is also known as
A
Circumferential Stress ; Hoop Stress ; Radial Stress
4
Q
The total force
acting at the rear of the
tank F must equal to the
total longitudinal stress on
the wall 𝑃𝑇 = 𝜎𝐿 𝐴𝑤𝑎𝑙𝑙 .
Since t is so small
compared to D, the area
of the wall is close to π𝐷𝑡.
A
Longitudinal Stress
5
Q
Formula of Longitudinal Stress
A
𝝈𝑳 = 𝒑𝑫 / 4t
