Analysis of an Elliptic Membrane Under Pressure

Description

Calculate the stresses at point (D) of an elliptic membrane under a uniform outward pressure of magnitude 10 MPa.

File Name

Browse to drive letter:\Users\Public\Public Documents\SOLIDWORKS\SOLIDWORKS version\samples\Simulation Examples\Verification\Static_13.SLDPRT and open the file.

Study Type

Static.

Mesh Type

Shell mesh.

Shell Parameters

Shell thickness = 0.1 m - Thin shell formulation.

Meshing Parameters

Use a Global Size of 0.14 m.

Material Properties

Modulus of elasticity = 210 X 10³ MPa, Poisson's ratio = 0.3.

Modeling Hints

Due to symmetry, only a quarter of the plate is modeled.
