Problem Specification
In this tutorial, we'll analyze the plane shell with stiffeners shown in the figure below.
All edges are clamped. A constant pressure of 0.05 N/mm^{2}acts on the underside of the shell (i.e. the pressure acts in the +z direction). Since the geometry and loads are symmetric about both the x and y-axes, we need to model only one-quarter of the structure. The dimensions of the plate and stiffeners are shown in the figure below which shows only one-quarter of the structure.
The Young's modulus E =7.3x10^{4} MPa and the Poisson ratio is 0.33.
Print out this page and have it on hand so that you can easily refer to the geometry and problem specification as you go through the tutorial.
