Dynamic Response and Optimal Design of Curved Metallic Sandwich Panels under Blast Loading

Table 5

Optimum panel designs for Case Study 1.

Panel	𝑅 (mm)	𝑇𝑖 (mm)	𝑇𝑜 (mm)	𝑇𝑐 (mm)	𝜌𝑓 (kg/m^3)	Mass (kg)	MaxD (mm)
							ANN	FE
P1	998.10	1.00	1.73	40.38	135	4.55	99.55	104.87
P1′	993.46	1.00	1.96	40.45	135	4.72	94.51	99.53
P2	427.15	3.22	3.99	58.66	355	14.99	10.41	11.65
P3	351.81	1.00	3.98	59.31	289	9.99	28.57	29.26

Note: P1 is the solution of minimum mass, P1′ is the solution of minimum mass with MaxD constraint of 95 mm, P2 is the solution of minimum MaxD, and P3 is the solution of minimum MaxD with mass constraint of 10 kg.
