| Abstract: | The stress/strain state of the delaminated sandwich beams is decomposed into two states: basic state and additional state. The additional state of delaminated sandwich beams is investigated using the theory of high order shear deformation. Differential equations of delaminated and undelaminated sectors are formulated and the polynomial solution to additional state is obtained. The actual example also shows that the polynomial solution above is precise in the whole beam domain except the transitional area. |
