摘要 本文研究了差分格式的人工粘性和动力屈曲准则对复合材料层合扁球壳非线性动力屈曲的影响 In this paper dynamic nonlinear axisymmetric buckling of laminated cylindrically orthotropic composite shallow spherical shells including third-order transverse shear deformation is investigated.Results of detailed parametric studies are presented to bring out the effects of artificial viscosity of difference scheme and dynamic buckling criterion on the buckling loads.
