Optimum panel designs for Case Study 2.

Panel	𝑅 (mm)	𝑇𝑖 (mm)	𝑇𝑜 (mm)	𝑇𝑐 (mm)	𝜌𝑓 (kg/m^3)	Mass (kg)	MaxD (mm)		EA (kJ)
							ANN	FE	ANN	FE
P4	417.27	3.48	3.34	58.37	353	14.99	11.62	11.35	39.51	39.58
P5	357.80	3.99	1.00	59.99	264	13.31	29.97	32.50	93.27	92.42
P6	999.97	3.99	1.81	59.99	137	11.21	38.49	47.21	122.14	121.63
P7	999.99	3.99	1.00	59.98	135	10.62	42.15	54.28	173.34	169.41

Note: P4 is the solution of minimum MaxD, P5 is the solution of maximum EA with MaxD constraint of 30 mm, P6 is the solution of minimum MaxD with EA constraint of 120 kJ, and P7 is the solution of maximum EA.
