Full TextAbstract
Material discontinuity could cause in-plane stress gradients that it arises interlaminar stresses in regions of sudden transition of material properties. A layerwise laminated beam theory that is a modification of a layerwise laminated plate theory are developed and it is used to analyze analytically the interlaminar stresses at material discontinuities in rotating composite beams. Equations of motion are obtained by using Hamilton’s principle. It is assumed that the beam is divided into two regions with different layups which are joined together. The predicted interlaminar stress distributions at the ply interfaces are shown to be in good agreement with comparative three-dimensional finite element analysis.
