Abstract
This study presents applicability of the absorbed energy evaluation method for a high-strength wire net of different shapes to be used for tornado missile protection equipments. The dynamic load-deformation relationship of high strength wire net of 40mm mesh and 50mm mesh were obtained by dynamic tensile tests. In order to confirm energy absorption ability of the net, free drop impact tests with heavy object were conducted. It was cleared that the absorbed energy of the net had to be calculated as square of dimensions long when ratio of length to width was less than 1 and the method was available if the aspect ratio were less than 2. As a result, it is found that the proposed evaluation method could estimate energy absorption ability of wire nets of different shapes by considering the limited conditions mentioned above.
