Structural Response of the SATCOM Antenna to a Blast Loading,
Abstract
The accuracy of the ADINA finite element program in modeling the transient response of a dish shaped antenna has been evaluated. Computed strain histories were compared with strain gage records from a simulated nuclear blast test performed on the antenna. With an 839 degrees-of-freedom finite element model, the program reproduced the salient features of the response, although a close correspondence between computed and test results was not realized. The study, however, did demonstrate that the model is sufficiently accurate for survivability estimates. (Author)
