Elliptic Membrane Under Pressure

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

File Name: Open drive letter:\Users\Public\Public Documents\SOLIDWORKS\SOLIDWORKS version\samples\Simulation Examples\Verification\NAFEMS_IC9.SLDPRT.

Study Type

Static

Mesh Type

Shell mesh

Shell Parameters

Shell thickness = 0.1 m - Thick shell formulation

Material Properties

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

Modeling Hints

Due to symmetry, model only a quarter of the plate.

Results

Component	Reference	SOLIDWORKS Simulation
Normal SY stress at point D (MPa)	92.70	91.56
