摘要
对拉氏分析方法的基本原理和一般处理方法进行了回顾,给出了路径线法计算流程,进一步地,将自编的LAMP程序应用到一维应变波传播的数值模拟中,以验证程序的正确性和可靠性,结果表明:LAMP是可靠有效的.在平板撞击实验结果的基础上,引入LAMP程序得到了新型碳酚醛材料高应变率下的一维应变本构关系,扩展了拉氏分析方法的应用.
The basic principle of Lagrangian analysis method （LAM） and the general compute methods were reviewed,and the computation flow chart of path line method was given. Further,in order to verify the correctness and reliability of the self-program,LAMP （Lagrangian analysis method procedure） was applied to the simulation of 1-D strain wave propagation. Results indicate that LAMP is reliable and effective. Based on the result of high speed impact experiment result and LAMP,1-D strain constitutive relation of NTCRB （new type carbon-reinforced bakelite） at high strain rates was constructed,thus extending the applications of the Lagrangian analysis method.
