Defining a Layered Material Stack
There is often a situation when different layered materials are stacked on top of each other to build a composite laminate for example a laminate having the stacking sequence [A/B/C/B/A] where A, B, C are three different layered materials or sub-laminates.
To simplify such modeling, use the Layered Material Stack node, which can be added under the Materials node within a component. In Layered Material Stack, you define the position and laminate coordinate system similar to in a Layered Material Link. You do however get a possibility to link multiple layered materials in the stacking order.
Note that it is also possible to add a Layered Material node directly under the Layered Material Stack node.
An example of a layered material stack having three different layered materials is shown in Figure 3-12.
