Özet:

 

In this article a new parameter is introduced that optimizes  penetration depth of a long rod penetrating into a semi-infinite  target.  This parameter helps to optimize penetration depth when the  projectile is subjected to transverse loading.  This parameter is  defined using a simple assumption governing bending moment and  deflection of the rod as well as the experimental observation of long  rod penetrators having aspect ratios (L/D) of greater than 30.  In  this article the length of the rod that sustains allowable bending  stress but does not fail is calculated.  Using the results of the  bending analysis and solution of the Alekseevskii & Tate (AT)  equation, an analytical method to optimize crater depth for long rod  penetrators of L/D > 30 is obtained.  The result of the optimization  shows a 14% increase in penetration depth.  Also the results of the  optimization are compared with the experimental results.
