Abstract：Based on elasticity theory, the stress and the strain of certain part of laminated cylinders with different materials laminated at radical direction were analyzed under axial pressure. With the consideration of threedimensional stress influence， the elastic solution of each layer was obtained respectively. The recursive relationship from laminated cylinder inner boundary to outer boundary was established based on the deformation coordination relationship among layers. The stress and the strain at any point within laminated cylinder were achieved according to the boundary conditions. Taking three different laminated columns as examples， the elastic stress and strain were analyzed. Because the influence of extrusion force caused by different Poisson′s ratio in each layer is considered in the proposed theory， the theoretical results are well consistent with those from finite element software.
