本研究将回传射线矩阵分析法延伸至包含基于第一剪切变形理论之复合材料层合梁在冲击力作用下之瞬态反应。为了验证所提出的分析方法的有效性，我们分析了一个层合悬臂梁模型在考虑第一剪切变形和转动惯量的影响下的速度响应。然后，采用回传射线矩阵分析法（RRM）求解了复合材料层合梁在半周脉冲力和矩形脉冲力作用下的瞬态响应。给出了复合材料层合梁中多次反射和散射波的回传射线矩阵。分析了非对称铺层顺序对冲击载荷类型和轴弯剪耦合效应的影响。文中还强调了梁模型对瞬态响应计算结果的影响。总之，与有限元方法相比，所提出的方法提供的结果是在良好的协议与以前的研究结果。RRM的优点是求解过程更简单、更快，需要的计算元素更少。
This study extends reverberation-ray matrix (RRM) analysis to include the transient responses of laminated composite beams based on the first shear deformation theory (FSDT) subjected to impulse force load. To validate the developed analysis method, we analyze the velocity response of a laminated cantilever beam model under considering the effect of the first shear deformation and rotary inertia. The transient responses of the laminated composite beam under a half-cycle pulse force and a rectangular pulse force are then solved by the reverberation-ray matrix analysis method (RRM). The reverberation-ray matrix that represents the multi-reflected and scattered waves in the laminated composite beam is demonstrated. The influence of the impact load type and the axial–flexural–shear coupled effects due to asymmetric ply stacking sequences are analyzed. The beam model effects on the calculation results for transient responses are also emphasized. In summary, compared with the finite element method, the proposed approach provides results that are in good agreement with previous findings. The advantage of RRM is that the solution process of RRM is simpler and faster, and requires fewer computational elements.
