圆柱壳瞬态波正交各向异性回传矩阵法
The equations of motion governing the axisymmetric elastic deformation of finite orthotropic cylindrical shells , involving the effect of transverse shear and rotational inertia , are derived . by applying the reverberation method , the displacement and the resultant forces of the shell in the phase space are expressed . then the transient waves in the finite orthotropic cylindrical shell subjected to the axisymmetric impact are obtained by using inverse laplace transforms . furthermore , the transient solutions are decomposed to the generalized ray integrals and computed numerically
分析了计及剪切变形和转动惯性的有限长正交异性圆柱壳中弹性瞬态波的传播问题，采用回传矩阵法，在相空间中给出了位移和内力的表达式。再利用laplace逆变换，得到正交异性圆柱壳受轴对称冲击作用时弹性瞬态波解，然后将其分解为若干广义射线积分之和，并用数值方法求解之。
