ST7-1.40.50.4 Composites with Core
Laminate composites often employ a light-weight core to increase the section depth which increases the stiffness and strength in bending. Modelling core in Strand7 can be achieved in a few different ways we will cover the two most common methods in this document: as a ply definition and as a solid (brick) element between two plate elements.
The simplest way to model core is to include it as a ply in the laminate material property definition. Table 1 below shows that the chosen honeycomb core...
