Pressure Vessel Simulator

Pressurize a thin-walled cylinder or sphere in 3D and watch the hoop stress climb to twice the longitudinal stress, which is why cylinders split along their length, not around. The wall heats with the von Mises stress; read the safety factor, the required wall thickness, and whether thin-wall theory even applies.

Drag to orbit, scroll to zoom. Press Pressurize to ramp the pressure; the bold red band is the hoop stress, the thinner band is the longitudinal stress.

Parameters

Pressure & size
2 MPa
500 mm
6 mm
1500 mm

Thin-wall theory assumes r/t ≥ 10. The info bar flags it red when the wall gets too thick for these formulas.

Material
250 MPa

Optional. The charts and summaries already update live as you drag any parameter; this just forces an immediate full recompute.

Analysis Charts

The stress charts show how the wall stresses grow with pressure and shrink with thickness; the sizing charts tell you the wall you need and whether thin-wall theory still applies. The teal marker is the current value. Drag any parameter and every curve updates live.
