| 摘 要： | 研究复合材料加肋层合板结构受冲击载荷作用下的瞬态波传播.加肋层合板模型被处理成层合板的弯曲运动与层合梁的扭转与弯曲运动的耦合连续模型.通过Laplace变换,并采用回传射线矩阵法(MRRM),基于一阶剪切变形层合板理论,确定复合材料加肋层合板结构中传播的各条射线群.采用FFT变换,计算各种冲击载荷作用下加肋层合板结构的短时瞬态响应,并分析讨论脉冲类型对加肋层合板结构短时瞬态响应的影响.

| Abstract: | The transient wave propagation in the stiffened laminated composite plates subjected to impact loads is studied.The rib-stiffened laminated plates are modeled as the coupling continuous system in which the flexural motion for the laminated plate is considered,and the flexure and torsion are taken into account for the laminated stiffeners which are modeled as the beams.Through the Laplace transform,on the basis of the first order shear deformation laminated plate theory,each ray group propagating in the stif... |
