Experimental and Simulation Study on Damage Enhancement of Focused Discrete Rods to Structures
摘要
Abstract
To investigate the damage effects of focused discrete rod warheads,a typical cylindrical target structure perforated by the focused discrete rod was designed.Through AbaqusTM finite element simulation and statics experimental tests,the damage ef-fectiveness of the focused discrete rod warhead on the structure was simulated and experimentally validated.The results indicate that under tensile loading,the ultimate load of the cylindrical structure perforated by the focused discrete rod is 19.22%of that of the unperforated cylinder,while the traditional fragment-perforated cylinder reaches 91.08%.Consequently,the ultimate load of the focused discrete rod-perforated cylinder is reduced by 71.86%compared to the traditional fragment-perforated cylinder.Under compressive load conditions,the cylindrical structure shows coupled buckling and fracture failure,with reduced stress concentration around the perforation.The ultimate load of the focused discrete rod-perforated cylinder is 68.76%of that of the unperforated cylinder,whereas the traditional fragment-perforated target cylinder reaches 93.84%.The structural ultimate load of the focused discrete rod-perforated cylinder is decreased by 25.08%compared to the fragment-perforated target,highlighting the differences in damage effects under various loading modes.The numerical simulation results and experimental data show good consistency in load response magnitude and failure trends,with the maximum relative error controlled within 15%,validat-ing the reliability of the research method.关键词
