The sandwich panel modeled in this tutorial is shown below. The contour and text plots on the model indicate the solution's failure criteria, outputting the inverse reserve factor (IRF) that measures the composite failure with critical values ranging from one and upward.
The sandwich panel is composed of a foam core and a high tensile strength (T700) carbon fiber reinforced plastic. The panel is 300 mm x 300 mm x 16.6 mm. It is clamped on all sides and subjected to a uniform pressure of 0.1 MPa. It consists of the following lay-up:
+/- 45° UD fabric
90° UD fabric
+/- 45° UD fabric
15 mm foam core
3 x 90° UD fabric
Note: Results shown in this tutorial may differ slightly from the results displayed for your model.
