How to define a Property model in Femap?

Modeling Property

Properties are used to define additional analysis information for one or more elements. Most property data are geometric (thicknesses, areas, radii, etc.), but properties also specify mass and inertia and select the materials to be used.

1.    Model - Property

 2.    Define Property

-    Define Property Dialog Box
There are many different dialog boxes used for creating the various property types since different values are required for nearly every element type. Near the top of each dialog box however, you will notice a group of controls which are used to set various parameters for the property to be created.


For an element to reference a property, both the property and the element must be the same type. The only exception is that there is no distinction between linear and parabolic properties. In fact both linear and parabolic elements can reference the same property.

-    Elem/Property Type
The Elem/Property Type… button, used to choose a different property type, can be found here also. This button will display the same dialog box as described in the Model, Element command.


-    Define Property - BEAM Element Type

-    Material drop-down list allows you to choose the material to be referenced by the property.
-    Material “icon button” next to the Material drop-down list can be used to create a new material.

This is the same as using the Model, Material command, except that the Define Property dialog box is still visible and the resulting material ID will automatically be entered into the list.

-    Shape drop-down list allows you to choose Cross-Section



-    Cross Section Definition, Shape drop-down can be used to define cross-section



-    Define Property - BEAM Element Type – Ready


Copying Properties

To create a property that is similar to another in your model, you do not have to enter all of the property values manually. Pressing the Copy button will display a list of all existing properties. When you choose a property from the list, the property values will be copied from that material and displayed in the current property creation dialog box. You can then modify any of these values, or even change your mind and copy a different property, before pressing OK to create the new property.
Copying is only useful when you copy properties of the same or similar type. When you copy properties of the same type, all values are directly transferred to the new property. If you copy a property of one type into a property of a different type, FEMAP converts the property to the new type, but many of the property constants may be meaningless. If the property types are similar, like a bar and beam, the similar properties will be copied. If you attempt to copy a plate property to a beam, or vice versa, you will get meaningless constants. You should review carefully any properties which you copy between different types.

Working with Property Libraries

Property libraries allow you to create standard properties that you can use over and over again in many different models. When you press Save, the current property is added to the property library file. Pressing Load will display a list of the properties in the library and let you choose one to be loaded into the property creation dialog box. Just like Copy, you can then modify the values before pressing OK to create the property. Also, just like Copy, when you load a property of a different type it is automatically converted. The property ID, Color, Layer and Material are not saved in the library, nor updated when a property is loaded from the library. For more information on libraries, see Section 2.6.2.10, "Library/Startup" and Section 4.3.6, "Library Selection" of the FEMAP User’s Guide.

How to define a Material model in Femap?

1. Model Material 2. Define Material 3. Material Type FEMAP supports eight types of materials: These material formulations allow you to simulate different material characteristics. FEMAP supports four regular material types and a general tabular data type: 1. Isotropic: Constant properties in all directions. All properties entered as a single value. 2. Orthotropic (Both 2-D and 3-D): Material properties are direction dependent. Parameters defined in two planar directions or three principal directions. 3. Anisotropic (Both 2-D and 3-D): Similar to Orthotropic except more general. Specify parameters as a general 3x3 (2-D) or 6x6 (3-D) elasticity matrix. 4. Hyperelastic: Materials subject to large deformations, such as rubber. Input distortional and volumetric deformation or stress/strain data. Limited solver support - many solvers do not support this material type - check your solver before using this material type. 5. General (Other Types): Solver specific typ...

What are the simplest method for Creating Geometry in Femap?

Image
Creating Geometry A geometry can be directly imported from many CAD or design system into FEMAP. Also, a geometry can be created directly in FEMAP using wireframe and solid modeling tools. Points, lines, and curves are the foundation blocks for a model. There are many options in FEMAP for creating points, lines and curves under the Geometry command. Understanding the advantage of different options for creating smoothly a geometry is relevant. Creating Points Points are used for constructing other geometry or finite element data. You may also apply loads and constraints to points, and FEMAP will automatically apply them to nodes attached to the points. Points are similar to nodes in that they are simply located at a specific location. Unlike nodes, however, they are not a finite element entity and are not translated to analysis programs. Instead, they are used for defining geometry. Just as elements reference nodes, curves reference points. The simplest method to create a point ...
