2D Structural Analysis

Workshop 4.2 - Goals

-Workshop 4.2 consists of a 2 part assembly representing a pressure cap and retaining flange (full model shown below).

-We will solve it as a 2D axisymmetric model (shown on next page).

Workshop 4.2–Assumptions

2D axisymmetric model assumptions:

-The retaining ring is fixed at its mounting holes.

-The contact region between the parts is frictionless.

-The base of the pressure cap is constrained using a compression only support.

Note: due to the presence of the bolt holes the structure is not truly axisymmetric.

Workshop 4.2 – Project Schematic

Open the Project page.

From the Units menu verify:

-Project units are set to “Metric (kg, mm, s, C, mA, mV).

-“Display Values in Project Units” is checked (on).

1.Double click “Static Structural” analysis type to add a new system.

2.RMB the Geometry cell and request “Properties”.

3.In the “Analysis Type” field specify “2D”.

Once this setting is made the properties window may be closed if desired.

Note this setting indicates the model to be analyzed is not a full 3D model but represents a symmetry section. It is important that this is set prior to importing geometry as this setting cannot be changed after the import.

4.Double click the “Engineering Data” cell to add material properties.

5.With the “General Materials” library highlighted choose the ‘+’ next to “Stainless Steel” to add the material to the project.

6.“Return to Project”.

Workshop 4.2–Geometry Setup

7.From the “Geometry” cell, RMB > “Import Geometry” and browse to: “Axisym_pressure_2D_12.x_t”.
