Supports

The laminated plate will require fixed displacement boundary conditions for each of its four sides. First orient the the view such that, you are looking down the z axis onto the xy plane. The y axis should be pointing upward and the x axis should be pointing to the right. The support on the left side of the plate will be dealt with first. In order to specify a fixed displacement, (Right Click) Static Structural < Insert < Displacement. Rename Diplacement "Displacement" to "Left Side Displacement". Next, use the edge selection filter, select the left plate side and apply it to the geometry selection for the Displacement condition. Next, set the y and z components of the displacement to zero while leaving the x component free. Repeat this process for the right side of the plate. Rename "Displacement 2" to "Right Side Displacement". Note that for the right side the displacement conditions will be the same as the left side. Now, the top side will be deal with. Once again insert a Displacement condition. Rename "Displacement 3" to "Top Side Displacement". Use the edge selection filter to select the top edge and then apply it as the geometry selection. Next, specify the x and the z component of the displacement to zero while leaving the y component free. Repeat, this process for the bottom edge. Rename "Displacement 4" to "Bottom Side Displacement". The displacement components for the bottom side are the same as those for the top side.

Pressure

To create the uniform pressure (Right Click) Static Structural > Insert > Pressure. Then apply the face of the plate as the geometry selection and set the magnitude of the pressure to 1 Pa.

In order to create the first command snippet (Expand) Geometry > (Right Click) Surface Body > Insert > Commands. Many commands are needed to specify the composite material properties of the laminate plate. These commands are listed below in between the two lines of asterisks. Copy and paste the commands below into the Commands snippet, that you just created. Notice, that the purpose of each command is displayed to the right.

In order to create the second command snippet (Right Click) Static Structural > Insert > Commands. Next, copy and paste the commands listed below in between the lines of asterisks into the second Command Snippet.
