"Evaluation of Low-Velocity Impact Response of Honeycomb Sandwich Structures Using Factorial-Based Design of Experiments, Journal of Sandwich Structures and Materials, 14(3), pp. 339-361. Description: 3^3 Factorial measuring 3 responses at 3 levels of 3 factors in 54 runs (2 reps ate each of 27 combinations of factors). Factor A: Angle Difference Between Successive Prepreg Layers -1=30, 0=45, +1=60 Factor B: Number of Prepreg Layers -1-4, 0=8, +1=12 Factor C: Number of Adhesive Layers -1=1, 0=2, +1=3 Response X = Energy Absorbed (Joulles) Response Y = Peak Contact Load (kN) Response Z = Maximum Deflection (mm) Variables/Columns Sample # 7-8 Coded Factor A 15-16 Coded Factor B 23-24 Coded factor C 31-32 Energy Absorbed 34-40 Peak Contact Load 42-48 Max deflection 50-56
