Optimal Design of Metallic Corrugated Sandwich Plates to Blast Loading
Optimal designs of the resistance of metallic corrugated sandwich plates under blast loading are studied numerically and analytically. The dynamic response of metallic sandwich plates under blast loading is numerically analyzed. Comparisons among the corrugated sandwich plates made of the same material and equivalent weight are conducted. The study of weight optimization is carried out, such as the relative core density, core height, the ratio of core height to half-length of the unit, and the thickness ratio of the top face sheet to bottom one. Based on the optimal designs, the sandwich plates possessing better performance are obtained. Three-dimensional finite element (FE) simulations are performed and the FE predictions are in good agreement with the theoretical predictions.
