Femap Express in Solid Edge
Femap Express.doc (Size: 163.5 KB / Downloads: 66)
Femap Express analyzes the stress, displacement, and vibration characteristics of a part. You can display the results on your computer, or save the results to a file. For example, you can define pressure loading and constraint parameters to determine the stress characteristics of the part.
Workflow Overview
The steps required to perform an analysis on a part consist of:
Defining the type of analysis (Stress or Modal) and analysis settings
Defining a material for the part
Defining the forces acting on the part (Stress analysis only)
Defining the constraints on the part
Processing the input
Displaying the results
Defining the Analysis Type and Settings
When you select the Femap Express command, the Femap Express SmartStep ribbon bar is displayed. If no previous analysis has been performed on the model, the Select Body Step is active.
For part documents (.PAR), if a solid body exists in the document, it is automatically selected. If a disjoint solid body exists, a warning message is displayed.
During this step, you can use the Analysis Type option on the ribbon bar to specify whether you want to perform a Stress or Modal analysis:
A stress analysis analyzes how pressure or force acts on a part.
A modal analysis analyzes the vibration characteristics of a part to determine its natural frequencies.
You can also use the Analysis Settings dialog box to control the mesh resolution and animation speed. You can also set these values anytime before you process the input.
Sheet Metal Parts
To perform an analysis on a part in a sheet metal document (.PSM), you must select an existing mid-surface feature. If a mid-surface feature does not exist, you can use the Mid-Surface command in the Sheet Metal environment to construct a mid-surface feature.
Defining the Part Material
If you have already defined a material for the part using the Material Table, the existing material is listed in the Select Material box on the ribbon bar. You can also use the Material button to display the Material Table to change the material or edit its properties.
Only isotropic materials are supported for analysis. Isotropic materials include most of the metal and plastic materials in the material table. Anisotropic materials, such as wood, cannot be analyzed. Anisotropic materials are automatically excluded from the materials list.
Defining the Forces Acting on the Part
If you are performing a stress analysis, the Load Definition dialog box allows you to add, edit, and delete loads on the part. The dialog box steps you through the load definition process:
Defining the load name, type, and value
The faces which carry the load
The load direction
You can apply one or more loads to the part. The loads can be force or pressure loads, using a load value and working unit you define. After you define the load name, type, and value, you can select the faces and direction to apply the load. These would typically be the faces which carry the load in the physical assembly (A).
