AFNOR SSLS06: Thin-walled cylinder under uniform radial pressure
1. Problem definition
-
Material properties:
- Young's modulus, E = 210 GPa
- Poisson ratio, nu = 0.3
-
Thickness properties:
- Thickness: 20 mm
-
Supports:
- Fix translation in Z on one end
-
Loads:
- Internal pressure: 10 kPa
2. Songeya model
Model only one quarter of the cylinder and impose symetry boundary conditions
3. Results
3.1 Total deformation
3.2 Membrane stresses
