VMFEBSTA-LE1
Linear Elastic Analysis on an Elliptical Membrane

Test Description

An elliptical membrane with thickness 0.1m is modeled with symmetry boundary conditions. Uniform outward pressure is applied at outer edge BC. Linear elastic static analysis is performed on the model.

Geometric PropertiesMaterial PropertiesLoading

Thickness = 0.1m

Origin to D = 2.0m

Length DC = 1.25m

Origin to A = 1.0m

Length AB = 1.75m

Curve AD: (x/2)2 + y2 = 1

Curve BC: (x/3.25)2 + (y/2.75)2 = 1

Boundary Condition:

Ux = 0 along AB
Uy = 0 along CD

E = 210E+03 Mpa

υ = 0.3

Outward pressure at

BC = 10 Mpa
