02Facesheet thickness was found to have the most significant effect on the stress values of the sandwich panel.

Application

Design takeaway

How to apply

When designing composite sandwich panels, conduct a design of experiments using Taguchi methods to explore the parameter space and employ GRA for optimizing multiple performance criteria simultaneously.

Project actions

01When choosing your design parameters, think about how they might interact.
02Consider using statistical tools to analyze your results, not just qualitative observations.

Method & Evidence

AimTo determine the optimal combination of facesheet thickness, core height, and panel width for a composite sandwich structure to maximize its strength and stiffness.

MethodExperimental design and multi-criteria decision-making analysis

ProcedureAn L9 orthogonal array was used to systematically vary facesheet thickness, core height, and panel width. Sheet stresses and shear stresses were calculated for each configuration. Taguchi analysis was performed to identify optimal parameter levels, followed by PCA-assisted Grey Relational Analysis (GRA) for multi-response optimization. ANOVA was used to assess the significance of each design factor.

ContextStructural engineering and materials science, specifically composite sandwich structures.

Variables

DV["Sheet stresses","Shear stresses"]

CV["Material properties of the composite","Loading conditions","Manufacturing process"]

Strengths & Limitations

Strengths

+Systematic approach using Design of Experiments (DOE).
+Application of a hybrid optimization technique for multi-response optimization.

Limitations

The number of parameter levels tested was limited by the orthogonal array, and other factors not studied could also influence performance.

Reliability & validity

Reliability is supported by the use of orthogonal arrays and statistical analysis. Validity is enhanced by the multi-faceted optimization approach (Taguchi, GRA, PCA) and ANOVA for factor significance.

Think critically

How might the optimal parameters change if different failure modes, such as delamination or buckling, were considered in the optimization process?
