Shell Parameters
Shell thickness = 0.12" - thin shell formulation.
Material Model
Linear elastic isotropic.
Material Properties
Modulus of elasticity = 1 x 107 psi, Poisson's ratio = 0.3162.
Modeling Hints
Due to symmetry, only a quarter of the plate is modeled. Draft quality shell mesh is used.
Restraints and Loads
All edges are simply supported. The pressure load is applied as follows:
Results
The load parameter versus the deflection ratio at the center of the plate is in good agreement with analytical results.
The results of the nonlinear analysis have been processed by a graphing software to generate the above graph.
