Now, we have specified the structural element type.
PLANE42 is now defined and assigned to reference 1. Your Element Types window should look like the figure below.
Note: PLANE42 is used for 2-D modeling of solid
structures. The element can be used either as a plane element (plane stress
or plane strain) or as an axisymmetric element. The element is defined by
four nodes having two degrees of freedom at each node: translations in the
nodal x and y directions. For more details about this or other Element types,
see ANSYS help
Alternative commands for executing the above precedure are:
ANSYS INPUT -> /prep7<CR>
ANSYS INPUT -> et,1,42 <CR>
The next step is to specify the material properties of the plate. There are
2 ways of doing this.
Method
1
PREPROCESSOR -> Material
Props
MATERIAL PROPS -> Material
Models
Then, the window "Define Material Model Behavior" will appear. You should double click on each of the following:
Structural -> Linear -> Elastic -> Isotropic
After you double click on Isotropic, you will see this window.
Then
enter the value for Young Modulus and Poisson Ratio given in this problem.
Click OK
Note: In the cases where multiple materials are used, you can specify the
properties and assign them to other material numbers (2, 3, 4, etc.)
Method
2
PREPROCESSOR -> Material Props
MATERIAL PROPS -> Material LibraryMATERIAL LIBRARY -> Import Library
You
should then see the following window, prompting for the units used in this
analysis. Click on BIN
and OK.
Following is the directory where the material property files for different types of materials are.
C:/Program Files/ANSYS Inc/v70/ANSYS/Matlib/fileStl_AISI-304.BIN_MPL
Then, the following window should appear.
Now we have defined the material property of this rectangle and its structural element type. Then we will move on to meshing the body into many finite elements.
REMEMBER TO SAVE YOUR FILE OFTEN.
