摘      要：A six-variable geometrical nonlinear shear deformation laminatedtheory is presented by which normal stress and strain distributioncan be calculated. by considering some affective factors that wereneglected under the finite deformation condition, an improved vonKarman geometrical non- linear deformation-strain relation is usedfor large deformation analysis. After analyzing the bending problemof laminated plates, and comparing it with 3-D elasticity solutionsand *** five-vari- able simple higher-order shear deformationlaminated theory, we can conclude that a satisfactory cal- culationprecision has been achieved, which shows that is especially suitablefor the calculation in the condition of large deformation and thelaminated thick plate analysis.
