APPROXIMATE FORMULA FOR NORMAL IMPACT OF A FINITE ELASTIC BEAM BY A SEMI-INFINITE ELASTIC ROD

    摘要
  • 摘要: 本文对具有初速的半无限长弹性杆与初始静止的有限长弹性梁的横向冲击问题进行了研究,用伽辽金方法求出了冲击力的近似解析解,并对结果进行了分析和讨论。

     

    Abstract: The normal impact of a finite elastic initially rest beam by a semi-infinite elastic rod with initial velocity is investigated in this paper. The approximate analytical solution of the impact force is obtained using the Galerkin method. Some discussions are made.
