Large Displacement of a Hinged Spherical Shell under Uniform Pressure Loading

Test Description

A spherical shell plate of length L = 1570 is simply supported along all 4 edges and a uniform distributed pressure load is applied on the shell surface. Elastic large deflection analysis is performed.

Geometic PropertiesMaterial PropertiesLoading
L = 1570
Shell mid-surface equation:
Z = 2.0285 x 10-4[X x (1570 - X) + Y x (1570 - Y)]
Boundary Conditions
Applied along edges:
Uy = 0
Ux = 0
Uz = 0
E = 69
ν = 0.3
Evenly distributed pressure load normal to shell surface with Pmax = 0.1

Results

Results are tabulated and displayed as in the NAFEMS manual.
