Abstract | The main objective of this research is to design multilayered steel bomb basket subjected to internal blast load using transient elastic analysis numerical model. AIR3D program and scaled blast data of normal blast wave reflection were used to calculate the properties of blast load. In this analysis, the outer diameter and height of bomb basket were limited to 75 cm. and 70 cm, respectively. The specimen was considered fail when its strain was over the yield strain. Each layer of bomb basket was separately modeled and then superimposed to determine the total designed blast load resistance. The numerical models of bomb basket were verified by previous experimental results. In this study, two types of steel bomb baskets were tested: One was two double layer 6mm-thick steel bomb baskets designed to resist blast load of 2.25 lb-TNT and the other was one triple layer 4mm-thick steel bomb basket designed for 1.85 lb-TNT blast load resistance. The double layer baskets were tested under the blast loads of 2.5 and 4.0 pounds of TNT (Trinitrotoluene) and the triple layer basket was tested with 5.0 lb-TNT which was placed in the middle of bomb baskets. The test results showed that (1) Double layer and triple layer steel bomb baskets have maximum blast load resistance equal to 4.0 and 5.0 lb-TNT, respectively. From this result, this designed method has safety factor about 1.8 for double layers and 2. 7 for triple layers (2) the triple layers steel bomb basket could resist blast load effectively and performed better than the double layers steel bomb baskets when use the same amount of material. |
