ASME B31.3 Basic Stress Calculations for Cylinder Under internal Pressure The average (through-thickness) circumferential and longitudinal (axial) stresses in a cylinder due to internal pressure can be calculated from equilibrium considerations. The circumferential stresses can be calculated from a longitudinal section, as shown in Fig. 4.3. The forces acting on that section must equilibrate, or, per Newton’s law, the parts on either side of the section will start acceleratin
