Study on the ballistic characteristics of cylindrical steel fragments penetrating soap target
Abstract：Objective To study the ballistic characteristics of different types of fragments,and provide useful references for the clinical treatment.Methods Twenty pieces of soap were respectively penetrated by steel fragments with 1 length-diameter ratio at the speed of 1 900m/s,1 100m/s,500m/s,and by steel fragments with 0.5,1,2 length-diameter ratio at the speed of 1 100m/s.Then the ballistic characteristics was analyzed and the differences between the ballistic characteristics were observed.Results When the length diameter ratio of the fragment was 1,the entrance diameter,depth and volume of ballistic cavity were increased in different degrees with the increased velocity,but the depth of the cavity was relatively smaller.When the speed was 1 100m/s,the entrance diameter of the cavity was decreased with increase length diameter ratio, and there was no significant difference between the volumes with increased depth.Conclusion The fragment`s speed and length-diameter ratios affect the ballistic diameter,depth and cavity volume in different degrees,which have great value for the diagnosis and treatment of trauma caused by high speed fragments.
