Analysis of stresses for composite laminated plates

根据文献 [1]所建立的位移场模型以及相应的位移形式的平衡方程 ,对简支层合板受一般载荷作用下的问题简化成求解其代数方程组的问题 .

Based on the double superposition hypothesis,a higher-order shear deformation theory for composite laminated plates is established,which has fixed unknowns and satisfies the stress and displacement continuity conditions at interfaces.For simply supported composite laminated plates under general load forms,the equilibrium equations are changed into the algebraic equations by using Fourier series,and then the analytic solutions are obtained.All of the results are compared with 3D-elastic solutions.The results are fairly satisfactory.
